Device Reset (with pull-up).
The active low –RESET input resets the device logic and returns the configuration of the device to the original factory default values or "stored values" in the NVRAM. –RESET is tied to VCC through a time-constant circuit for “Power-on-Reset” functionality. The module is ready to accept commands after a fixed amount of time (“X” Time) after power-on or reset.

*The SocketModem device may respond to a shorter reset pulse.
Reset Line Interface for the MT5656SMI, MT2456SMI, MT2456SMI-IP
The modem’s reset line employs a .01uF cap and a 10K pull up resistor. Care must be taken to ensure the system the modem is place into is not affected by the added capacitance of the reset line. It is not advisable to use an open collector driver in the embedded system's reset circuitry to drive a reset signal to the embedded modem and other I.C.s in the customer’s design. Rather, if an open collector driver is to be used, run that output to the modem only and use a separate driver for other embedded components. The modem’s reset signal may also be driven by a circuit that both sinks and sources current if desired. It is also important to note that these modems do not require an external reset. They have their own internal reset circuitry and voltage monitor and will function correctly even if the reset input is open.
Reset Wireless GSM/GPRS and CDMA
This signal is used to force a reset procedure by providing low level during reset of at least 500us. The signal is considered an emergency reset only. A reset procedure is already driven by internal hardware during the power-up sequence. If no external reset is necessary, this input can be left open. If used (emergency reset), it has to be driven by an open collector or an open drain.

Chapter 1 – Universal Socket Connectivity
Design Considerations
Good engineering practices must be adhered to when designing a printed circuit board (PCB) containing the SocketModem module. Suppression of noise is essential to the proper operation and performance of the modem itself and for surrounding equipment.
Two aspects of noise in an OEM board design containing the SocketModem must be considered: on-board/off-board generated noise that can affect digital signal processing. Both on-board and off-board generated noise that is coupled on-board can affect interface signal levels and quality. Of particular concern is noise in frequency ranges affecting modem performance.
On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is a separate, but equally important, concern. This type of noise can affect the operation of surrounding equipment. Most local government agencies have stringent certification requirements that must be met for use in specific environments.
Proper PC board layout (component placement, signal routing, trace thickness and geometry, etc.) component selection (composition, value, and tolerance), interface connections, and shielding are required for the board design to achieve desired modem performance and to attain EMI certification.
The aspects of proper engineering practices are beyond the scope of this designer guide. The designer should consult noise suppression techniques described in technical publications and journals, electronics and electrical engineering text books, and component supplier application notes.
PC Board Layout Guidelines
In a 4-layer design, provide adequate ground plane covering the entire board. In 4-layer designs, power and ground are typically on the inner layers. All power and ground traces should be 0.05 inches wide.
The recommended hole size for the SocketModem pins is 0.036 in. +/-0.003 in. in diameter. Spacers can be used to hold the SocketModem vertically in place during the wave solder process. A spacer should be placed on pin 32 and pin 64 of the SocketModem. A suggested part number for the spacer is BIVAR 938-0.130 for P1 (0.310in) option SocketModems. The spacers can be left on permanently and will not effect operation.
All creepages and clearances for the SocketModem have been designed to meet requirements of safety standards EN60950. The requirements are based on a working voltage of 250V. When the recommended DAA circuit interface is implemented in a third party design all creepage and clearance requirements must be strictly adhered to. The third party safety design must be evaluated by the appropriate national agency per the required specification.
User accessible areas: Based on where the third party design is to be marketed, sold, or used, it may be necessary to provide an insulating cover over all TNV exposed areas. Consult with the recognized safety agency to determine the requirements.
Note: Even if the recommended design considerations are followed, there are no guarantees that a particular
system will comply with all the necessary regulatory requirements. It is imperative that specific designs be completely evaluated by a qualified/recognized agency.

Chapter 1 – Universal Socket Connectivity
Electromagnetic Interference (EMI) Considerations
The following guidelines are offered to specifically help minimize EMI generation. Some of these guidelines are the same as, or similar to, the general guidelines but are mentioned again to reinforce their importance. In order to minimize the contribution of the SocketModem-based design to EMI, the designer must understand the major sources of EMI and how to reduce them to acceptable levels.
1. Keep traces carrying high frequency signals as short as possible.
2. Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for
ground and power distribution.
3. Decouple power from ground with decoupling capacitors as close to the SocketModem module power pins
as possible.
4. Eliminate ground loops, which are unexpected current return paths to the power source and ground.
5. Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series
inductors, common mode chokes, and shunt capacitors. Methods to decouple telephone lines are similar to decoupling power lines; however, telephone line decoupling may be more difficult and deserves additional attention. A commonly used design aid is to place footprints for these components and populate as necessary during performance/EMI testing and certification.
6. Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple
power lines are similar to decoupling telephone lines.
7. Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits.
8. Locate cables and connectors so as to avoid coupling from high frequency circuits.
9. Lay out the highest frequency signal traces next to the ground grid.
10. If a multilayer board design is used, make no cuts in the ground or power planes and be sure the ground
plane covers all traces.
11. Minimize the number of through-hole connections on traces carrying high frequency signals.
12. Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns
are better.
13. On 2-layer boards with no ground grid, provide a shadow ground trace on the opposite side of the board to
traces carrying high frequency signals. This will be effective as a high frequency ground return if it is three times the width of the signal traces.
14. Distribute high frequency signals continuously on a single trace rather than several traces radiating from one
point.
Handling Precautions
All electronic devices should be handled with certain precautions to avoid damage due to the accumulation of static charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of this static buildup, proper precautions should be taken to avoid exposure to electrostatic discharge during handling and mounting.

Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342D) 25
Chapter 1 – Universal Socket Connectivity
Canadian Labeling Requirements (for Dial-Up Modems)
The following requirements are established under section 69.3 of the Telecommunications Act for purposes of section 5 of the Telecommunications Apparatus Regulations.
Registered equipment shall bear the following identifying marks, and the Declaring Party shall ensure that these marks are permanently affixed to the equipment:
(a) The registration number — Specifications of this mark are given in the document: Self-Marking of the
Certification/Registration Number on Terminal Equipment — Application Procedure and Agreement; and
(b) The model identification number under which the product was registered.
A statement of compliance with Industry Canada requirements, such as the one given below, shall accompany each unit of equipment whether registered under this procedure or previously certified:
"This product meets the applicable Industry Canada technical specifications"
For terminal equipment intended for connection to loop-start or ground-start interfaces, the Ringer Equivalence Number (REN) must be calculated as per Section 1.8 of CS-03, Part I. A REN higher than that determined may be assigned by manufacturers to allow for production variations. The REN must be marked on the terminal equipment itself or added to the note below. A note similar to the following shall accompany each unit of equipment whether registered under this procedure or previously certified:
"The Ringer Equivalence Number is an indication of the maximum number of devices allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the RENs of all the devices does not exceed five".
Pursuant to section 69.3 of the Telecommunications Act, certified or self-declared TE will bear a valid identifying certification number or registration number. The marking of the certification or registration number on the product shall be as follows:
(a) TAC holder/DP will be responsible for permanently affixing the certification/registration number on the
TE. The certification/registration number (see example below) identifies Certified or self-declared TE to the public, representatives of the telecommunications common carriers, the Department, and other interested parties. The letter height must be no less than 1.5 mm and the letters must be legible without magnification.
(b) For integrated devices, e.g. a modem or one that is intended to become a sub-assembly of host
equipment e.g. a data terminal, computer etc. that are designed to interface directly with the network, the certification/registration number shall be affixed to the integrated device itself.
(c) The certification/registration number for a packaged TE will denote that the total package has been
registered. However, the marking will normally be placed on that unit of the package which connects to the network; e.g., in a PBX the marking will be placed on the common equipment which connects to the network, rather than on plug-in components which may be added later. The Terminal Equipment List will show the common equipment but not the standard station apparatus or any proprietary station apparatus.
(d) The marking format of the certification/registration number is as follows:
IC: XXXXXX-YYYYYYYY
Where:
• The letters "IC" have no other meaning or purpose than to identify the Industry Canada
certification/registration number, and
• “XXXXXX-YYYYYYYY” is the certification/registration number; “XXXXXX” is the Company Number¹
(CN); it consists of up to six alphanumeric characters (A-Z, 0-9) assigned by Industry Canada; and “YYYYYYYY” is the Unique Product Number (UPN); it consists of up to eight alphanumeric characters (A-Z, 0-9) assigned by the applicant. Other characters, (such as & # *-) may not be used. Alphabetic characters must be capitalized.
¹ Note: The Company Number of registered equipment ends with an alphabetic character.
(e) Certification Numbers granted prior to the implementation of the above marking format are
grandfathered.
(i) For previously certified TE, the self-marking format shall consist of the old certification number
preceded by “IC:” For example, if the certification number is “123 1234 A”, then the self-mark would read “IC: 123 1234 A”.
(ii) For a new model that is registered to a family of previously certified TE, the self-marking format
shall be: IC: XXXXXX-ZZZZZZZZ
Where:
• “XXXXXX” is the Company Number, as in (d) above; and
Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342D) 26
• “ZZZZZZZZ” is either the old certification number minus the old company number, or a new
Unique Product Number assigned by the applicant. For example, if a new model is registered to the family of products with certification number “123 1234 A”, and that the Company Number for the registration is “123A”, then the self-mark for this new model would read “IC: 123A-1234 A”. If the applicant decides to replace “1234 A” with a new UPN, say “5678", then the self-mark would read “IC: 123A-5678".

Programming the Modem
There are two ways to start flash programming a modem. It can be programmed
1. From “AT” mode
2. When the modem powers up.
The following table shows how a modem is programmed.
DTE Modem Comments
AT*FS\r This effectively “restarts” the modem so that it enters the boot code. Handshake Sequence
M’s Many M’s are sent (10 milliseconds apart) at 19200 baud.
This is where the handshake starts if the modem is just powered up.
U U is sent at 19200 baud if M’s are received within 100 milliseconds of
power up. If the M’s are not received within 100 milliseconds, then the modem starts up normally. If the AT*FS command is used, then
you have 1 second (1000mS) to perform the handshake. D Sent at 19200 baud. M M if can receive at 9600/19200/38400/57600/115200 I|J|K|L|M I if modem will be programmed at 9600

Other Supported Boot Code Commands
2.1 ATI0 - returns 000 or 247 for ISDN
2.2 ATI1 - returns boot code version number MM.mmn where MM = unique code for each different platform that has boot code mm = version number of boot code n = version letter of the boot code Examples: 2.05e, 2.12d, 35.15
ATI4- Boot code date and time.
Other Programming Concerns
1. The values programmed into Addresses 0000h, 0001h and 0002h should always be forced to C3h 00 01 (i.e., JP 100h).
This is because the boot code starts at address 100h, while all normal modem code starts at 200h. By
allowing 0000h to be programmed to a jump value other than 0100h, the boot code would be bypassed and no further upgrades could occur.
2. Addresses 0100h-01FFh through 70000h-7FFFFh should not be allowed to be programmed under normal circumstances, as this is the main body of the boot up code.
3. The packets sent to the modem must be presorted by address and aligned on 128 byte boundaries (i.e., each packet must start on an address that is a multiple of 128).
4. The packets should also be a minimum of 128 bytes with the non-programmed bytes set to the hex value of FF.
5. The packets sent to the modem must not span a 4K boundary (i.e., start the packet before it and go over the boundary in the middle of the packet).
6. The 10-millisecond delay between M’s at the beginning of the handshake is so that the modem can sync up to the start bit. If the M’s are sent one right after another, a data bit might be mistaken as a start bit.
7. Multi-Tech firmware files are in Intel Hex Format and must be read in and formatted into 128-4096 byte blocks before being sent to the modem.
Chapter 1 – Universal Socket Connectivity
Information about the Intel Hex Format
An Intel Format Hex File is a text file consisting of “records”, one per line, that start with a “:” character and include only digits 0-9 and letters A-F. There are three different record types: Extended Address Records, Data Records, and End of File Records.
Data records contain the actual data that is to be programmed into a device. The address contained in the data record needs to be combined with an extended address (by adding the extended address shifted four bits left to the data record address) to determine the actual programming address for the data. If no extended address record is before a given data record in the file, then the extended address value is assumed to be zero.
Data Record
Char Pos Field Type Value Description
1 Record Start “:” 2-3 Data Byte Count “NN”
4-7 Address “XXXX” Lower 16 bits of 20 bit address, most significant byte
8-9 Record Type “00” Data Record 10+N Data Bytes “YY..YY” The data bytes in hex. Each byte is two characters. NN+1,2 Checksum “ZZ” Zero minus the two’s complement addition of all data
NN+3,4 End of Line “\r\n” Carriage Return followed by a Line Feed Example Data Record in Intel Format :2000A0005BB66DDBB66CD8B060C183060D1B366DDBB66DDBB76FDFBF7EFDFBF6EDDBB66DD4
Maximum value is FF (which is 255 data bytes). Typical is 20h which causes the hex record to fit in 80 columns.

Pin 54 – “VC” This pin provided a reference voltage that is available from the data pump. This pin is not
supported on the MT5656SMI SocketModem.
Pin 55 – “~Voice” This function, when active, closes the relay to switch the handset from the telephone line to a
current source to power the handset where it could be used as a speaker and microphone interface to the modem. This pin is not provided on the SocketModem
Pin 57 – “LCS” (Line Current Sense) When enabled, the LCS input indicates whether the associated handset

Pin 58 – “Telout” (Telephone Handset Output). This pin is not supported on the SocketModem.
Pin 59 – “Telin” (Telephone Handset Input). This pin is not supported on the SocketModem.
Pin 60 – “Micm” (Microphone Modem Input). This pin is not supported on the SocketModem.
Pin 62 – “Micv” (Microphone Voice Input). This pin is supported on the MT5656SMI SocketModem in the same
way as the "SF" modem.

Chapter 2 – SocketModem (MT5600SMI & MT5656SMI)
SocketModem Parallel Interface
The modem supports a 16550A interface in parallel interface versions. The 16550A interface can operate in FIFO mode or non-FIFO mode. Non-FIFO mode is the same as the 16450-interface operation. FIFO mode’s unique operations are described in this chapter.
Overview
The modem emulates the 16450/16550A interface and includes both a 16-byte receiver data first-in first-out buffer (RX FIFO) and a 16-byte transmit data first-in first-out buffer (TX FIFO).
FIFO Mode Selected
When FIFO mode is selected in the FIFO Control Register (FCR0 = 1), both FIFOs are operative. Furthermore, when FIFO mode is selected, DMA operation of the FIFO can also be selected (FCR3 = 1).
FIFO Mode Not Selected
When FIFO mode is not selected, operation is restricted to a 16450-interface operation.
Receive Data
Received Data is read by the host from the Receiver Buffer (RX Buffer). The RX Buffer corresponds to the Receiver Buffer Register in a 16550A device. In FIFO mode, the RX FIFO operates transparently behind the RX Buffer. Interface operation is described with reference to the RX Buffer in FIFO and non-FIFO modes.
Transmit Data
Transmit Data is loaded by the host into the Transmit Buffer (TX Buffer). The TX Buffer corresponds to the Transmit Holding Register in a 16550A device. In FIFO mode, the TX FIFO operates transparently behind the TX Buffer. Interface operation is described with reference to the TX Buffer in both FIFO and non-FIFO modes.
Receiver FIFO Interrupt Operation
Receiver Data Available Interrupt
When the FIFO mode is enabled (FCR0 = 1) and receiver interrupt (RX Data Available) is enabled (IER0 = 1), receiver interrupt operation is as follows:
1. The Receiver Data Available Flag (LSR0) is set as soon as a received data character is available in the RX FIFO. LSR0 is cleared when RX FIFO is empty.
2. The Receiver Data Available Interrupt code (IIR0-IIR4 = 4h) is set whenever the number of received data bytes in the RX FIFO reaches the trigger level specified by FCR6-FCR7 bits. It is cleared whenever the number of received data bytes in the RX FIFO drops below the trigger level specified by FCR6-FCR7 bits.
3. The HINT interrupt is asserted whenever the number of received data bytes in the RX FIFO reaches the trigger level specified by FCR6-FCR7 bits. HINT interrupt is de-asserted when the number of received data bytes in the RX FIFO drops below the trigger level specified by FCR6­FCR7 bits.
Receiver Character Timeout Interrupts
When the FIFO mode is enabled (FCR0 = 1) and receiver interrupt (Receiver Data Available) is enabled (IER0 = 1), receiver character timeout interrupt operation is as follows:
1. A Receiver character timeout interrupt code (IIR0-IIR3 = Ch) is set if at least one received character is in the RX FIFO, the most recent received serial character was longer than four continuous character times ago (if 2 stop bits are specified, the second stop bit is included in this time period), and the most recent host read of the RX FIFO was longer than four continuous character times ago.
Transmitter FIFO Interrupt Operation
Transmitter Empty Interrupt
When the FIFO mode is enabled (FCR0 = 1) and transmitter interrupt (TX Buffer Empty) is enabled (IER0 =1), transmitter interrupt operation is as follows:
1. The TX Buffer Empty interrupt code (IIR0-IIR3 = 2h) will occur when the TX Buffer is empty. It is cleared when the TX Buffer is written to (1 to 16 characters) or the IIR is read.
2. The TX Buffer Empty indications will be delayed 1 character time minus the last stop bit time whenever the following occur: THRE = 1 and there have not been at least two bytes at the same time in the TX FIFO Buffer since the last setting of THRE was set. The first transmitter interrupt after setting FCR0 will be immediate.

IER – Interrupt Enable Register
(Addr = 1, DLAB = 0)
The IER enables five types of interrupts that can separately assert the HINT output signal (See the Interrupt Sources and Reset Control table in the IIR section of this chapter). A selected interrupt can be enabled by setting the corresponding enable bit to a 1, or disabled by setting the corresponding enable bit to a 0. Disabling an interrupt in the IER prohibits setting the corresponding indication in the IIR and assertion of HINT. Disabling all interrupts (resetting IER0 – IER3 to a 0) inhibits setting of any Interrupt Identifier Register (IIR) bits and inhibits assertion of the HINT output. All other system functions operate normally, including the setting of the Line Status Register (LSR) and the Modem Status Register (MSR).

Bits 7-4 Not used.
Always 0.
Bit 3 Enable Modem Status Interrupt (EDSSI).
This bit, when a 1, enables assertion of the HINT output whenever the Delta CTS (MSR0),
Delta DSR (MSR1), Delta TER (MSR2), or Delta DCD (MSR3) bit in the Modem Status Register (MSR) is a 1. This bit, when a 0, disables assertion of HINT due to setting of any of these four MSR bits.
Bit 2 Enable Receiver Line Status Interrupt (ELSI).
This bit, when a 1, enables assertion of the HINT output whenever the Overrun Error (LSR1),
Parity Error (LSR2), Framing Error (LSR3), or Break Interrupt (LSR4) receiver status bit in the Line Status Register (LSR) changes state. This bit, when a 0, disables assertion of HINT due to change of the receiver LSR bits 1-4.
Bit 1 Enable Transmitter Holding Register Empty Interrupt (ETBEI).
This bit, when a 1, enables assertion of the HINT output when the Transmitter Empty bit in the
Line Status Register (LSR5) is a 1.This bit, when a 0, disables assertion of HINT due to LSR5.
Bit 0 Enable Receiver Data Available Interrupt (ERBFI) and Character Timeout in FIFO Mode.
This bit, when a 1, enables assertion of the HINT output when the Receiver Data Ready bit in
the Line Status Register (LSR0) is a1 or character timeout occurs in the FIFO mode. This bit, when a 0, disables assertion of HINT due to the LSR0 or character timeout.

FCR – FIFO Control Register
(Addr = 2, Write Only)
The FCR is a write-only register used to enable FIFO mode, clear the RX FIFO and TX FIFO, enable DMA mode, and set the RX FIFO trigger level.
Bits 7-6 RX FIFO Trigger Level
FCR7 and FCR6 set the trigger level for the RX FIFO (Receiver Data Available) interrupt.

Bits 5, 4
Bit 3 DMA Mode Select
Bit 2 TX FIFO Reset
Bit 1 RX FIFO Reset
Bit 0 FIFO Enable
Not used
When FIFO mode is selected (FCR0 = 1), FCR3 selects non-DMA operation (FCR3 = 0) or DMA operation (FCR3 = 1). When FIFO mode is not selected (FCR0 = 0), this bit is not used (the modem operates in non-DMA mode in 16450 operation).
DMA Operation in FIFO Mode
RXRDY will be asserted with the number of characters in the RX FIFO us equal to or greater
than the value in the RX FIFO Trigger Level (IIR0-IIR3 = 4h) or the received character timeout (IIRO-IIR3 = Ch) has occurred. RXTDY will go inactive when there are no more characters in the RX FIFO.
TXRDY will be asserted when there are one or more empty (unfilled) locations in the TX
FIFO. TXRDY will go inactive when the TX FIFO is completely full.
Non-DMA Operation in FIFO Mode
RXRDY will be asserted when there are one or more characters in the RX FIFO. RXRDY
will go inactive when there are no more characters in the RX FIFO.
TXRDY will be asserted when there are no characters in the TX FIFO. TXRDY will go
inactive when the character is loaded into the TX FIFO Buffer.
When FCR2 is a 1, all bytes in the TX FIFO are cleared. This bit is cleared automatically by the modem.
When FCR1 is a 1, all bytes in the RX FIFO are cleared. This bit is cleared automatically by the modem.
When FCR0 is a 0, 16450 mode is selected and all bits are cleared in both FIFOs. When FCR0 is a 1, FIFO mode (16550A) is selected and both FIFOs are enabled. FCR0 must be a 1 when other bits in the FCR are written or they will not be acted upon.

Chapter 2 – SocketModem (MT5600SMI & MT5656SMI)
IIR – Interrupt Identifier Register
(Addr = 2)
The Interrupt Identifier Register (IIR) identifies the existence and type of up to five prioritized pending interrupts. Four priority levels are set to assist interrupt processing in the host. The four levels, in order of decreasing priority, are Highest: Receiver Line Status, 2: Receiver Data Available or Receiver Character Timeout. 3: TX Buffer Empty, and 4: Modem Status.
When the IIR is accessed, the modem freezes all interrupts and indicates the highest priority interrupt pending to the host. Any change occurring in interrupt conditions are not indicated until this access is complete.
Bits 7-6 FIFO Mode
These two bits copy FCR0.
Bits 5-4 Not Used
Always 0.
Bits 3-1 Highest Priority Pending Interrupt
These three bits identify the highest priority pending interrupt (Table below). Bit 3 is applicable only when FIFO mode is selected; otherwise, bit 3 is a 0.
Bit 0 Interrupt Pending
When this bit is a 0, an interrupt is pending; IIR bits 1-3 can be used to determine the source of the interrupt. When this bit is a 1, an interrupt is not pending

LCR – Line Control Register
(Addr = 3)
The Line Control Register (LCR) specifies the format of the asynchronous data communications exchange.
Bit 7 Divisor Latch Access Bit (DLAB)
This bit must be set to a 1 to access the Divisor Latch Registers during a read or write operation. It must be reset to a 0 to access the Receiver Buffer, the Transmitter Buffer, or the Interrupt Enable Register.
Bit 6 Set Break
When bit 6 is a 1, the Transmit data is forced to the break condition, i.e., space (0) is sent. When bit 6 is a 0, break is not sent. The Set Break bit acts only on the Transmit data and has no effect on the serial in logic.
Bit 5 Stick Parity
When Parity is enabled (LCR3 = 1) and stick parity is selected (LCR5 = 1), the parity bit is transmitted and checked by the receiver as a 0 if even parity is selected (LCR4 – 1) or a 1 if odd parity is selected (LCR4 = 0). When the stick parity is not selected (LCR3 = 0), parity is transmit and checked as determined by the LCR3 and LCR4 bits.
Bit 4 Even Parity Select (EPS)
When parity is enabled (LCR3 = 1) and stick parity is not selected (LCR5 = 0), the number of 1s transmitted or checked by the receiver in the data word bits and parity bit is either even (LCR4 =
1) or odd (LCR4 = 0).
Bit 3 Enable Parity (PEN)
When bit 3 is a 1, a parity bit is generated in the serial out (transmit) data stream and checked in the serial in (receive) data stream as determined by the LCR4 and LCR5 bits. The parity bit is located between the last data bit and the first stop bit.
Bit 2 Number of Stop GBITS (STB)
This bit specifies the number of stop bits in each serial out character. If bit 2 is a 0, one stop bit is generated regardless of word length. If bit 2 is a 1 and 5-bit word length is selected, one and one-half stop bits are generated. If bit 2 is a 1 and 6-, 7-, or 8-bit word length is selected, two stop bits are generated. The serial in logic checks the first stop bit only, regardless of the number of stop bits selected.
Bit 1-0 Word Length Select (WLS0 and WLS1)
These two bits specify the number of bits in each serial in or serial out character. The encoding of bits 0 and 1 is:
Bit 1 Bit 0 Word Length
0 0 5 Bits (Not supported) 0 1 6 Bits (Not supported) 1 0 7 Bits 1 1 8 Bits

The Modem Control Register (MCR) controls the interface with modem or data set.
Bit 7-5 Not used
Always 0
Bit 4 Local Loopback
When this bit is set to a 1, the diagnostic mode is selected and the following occurs:
1. Data written to the Transmit Buffer is looped back to the Receiver Buffer.
2. The DTS (MCR0), RTS (MCR1), Out1 (MCR2), and Out2 (MCR3) modem control register bits are internally connected to the DSR (MSR5), CTS (MSR4), RI (MSR6), and DCD (MSR7) modem status register bits, respectively.
Bit 3 Output 2
When this bit is a 1, HINT is enabled. When this bit is a 0, HINT is in the high impedance state.
Bit 2 Output 1
This bit is used in local loopback (see MCR4).
Bit 1 Request to Send (RTS)
This bit controls the Request to Send (RTS) function. When this bit is a 1, RTS is on. When this bit is a 0, RTS is off.
Bit 0 Data Terminal Ready (DTR)
This bit controls the Data Terminal Ready (DTR) function. When this bit is a 1, DTR is on. When this bit is a 0, DTR is off.

LSR – Line Status Register
(Addr = 5)
This 8-bit register provides status information to the host concerning data transfer
Bit 7 RX FIFO Error
In the 16450 mode, this bit is not used and is always 0. In the FIFO mode, this bit is set if there are one or more characters in the RX FIFO with parity
error, framing error, or break indication detected. This bit is reset to a 0 when the host reads the LSR and note of the above conditions exist in the RX FIFO.
Bit 6 Transmitter Empty (TEMT)
This bit is set to a 1 whenever the TX Buffer (THR) and equivalent of the Transmitter Shift Register (TRS) are both empty. It is reset to a 0 whenever either the THR or the equivalent of the TSR contains a character.
In the FIFO mode, this bit is set to a 1 whenever the TX FIFO and the equivalent of the TSR are both empty
Bit 5 Transmitter Holding Register Empty (THRE) [TX Buffer Empty]
This bit, when set, indicates that the TX Buffer is empty and the modem can accept a new character for transmission. In addition, this bit causes the modem to issue an interrupt to the host when the Transmit Holding Register Empty Interrupt Enable bit (IIR1) is set to 1. The THRE bit is set to a 1 when a character is transferred from the TX Buffer. The bit is reset to 0 when a byte is written into the TX Buffer by the host.
In the FIFO mode, this bit is set when the TX FIFO is empty; it is cleared when at lease one byte is in the TX FIFO.
Bit 4 Break Interrupt (BI)
This bit is set to a 1 whenever the received data input is a space (logic 0) for longer than two full word lengths plus 3 bits. The BI is reset when the host reads the LSR.
Bit 3 Framing Error (FE)
This bit indicates that the received character did not have a valid stop bit. The FE bit is set to a 1 whenever the stop bit following the last data bit or parity bit is detected as a logic o (space). The FE bit is reset to a 0 when the host reads the LSR.
In the FIFO mode, the error indication is associated with the particular character in the FIFO it applies to. The FE bit set to a 1 when this character is loaded into the RX Buffer.
Bit 2 Parity Error (PE)
This bit indicates that the received data character in the RX Buffer does not have the correct even or odd parity, as selected by the Even Parity Select bit (LCR4) and the Stick Parity bit (LCR5). The PE bit is reset to a 0 when the host reads the LSR.
In the FIFO mode, the error indication is associated with the particular character in the FIFO it applies to. The PE bit set to a 1 when this character is loaded into the RX Buffer.
Bit 1 Overrun Error (OE)
This bit is set to a 1 whenever received data is loaded into the RX Buffer before the host has read the previous data from the RX Buffer. The OE is reset to a 0 when the host reads the LSR.
In the FIFO mode, if data continues to fill beyond the trigger level, an overrun condition will occur only if the RX FIFO is full and the next character has been completely received.
Bit 0 Receiver Data Ready (DR)
This bit is set to a 1 whenever a complete incoming character has been received and transferred into the RX Buffer. The DR bit is reset to a 0 when the host reads the RX Buffer.
In the FIFO mode, the DR bit is set when the number of received data bytes in the RX FIFO equals or exceeds the trigger level specified in the FCR0-FCR1.

Chapter 2 – SocketModem (MT5600SMI & MT5656SMI)
MSR – Modem Status Register
(Addr = 6)
The Modem Status Register (MSR) reports current state and change information of the modem. Bits 4-7 supply current state and bits 0-3 supply change information. The change bits are set to a 1 whenever a control input form the modem changes state from the last MSR read by the host. Bits 0-3 are reset to 0 when the host reads the MSR or upon reset.
Whenever bits 0, 1, 2, or 3 are set to a 1, a Modem Status Interrupt (IIR0-IIR3 = 0) is generated.
Bit 7 Data Carrier Detect (DCD)
This bit indicates the logic state of the DCH# (RLSD#) output. If Loopback is selected (MCR4 =
1), this bit reflects the state of the Out2 bit in the MCR (MCR3).
Bit 6 Ring Indicator (RI)
This bit indicates the logic state of the RI# output. If Loopback is selected (MCR4 = 1), this bit reflects the state of the Out1 bit in the MCR (MCR2).
Bit 5 Data Set Ready (DSR)
This bit indicates the logic state of the DSR# output. If Loopback is selected (MCR4 = 1), this bit reflects the state of the DTR in the MCR (MCR0).
Bit 4 Clear to Send (CTS)
This bit indicates the logic state of the CTS# output. If Loopback is selected (MCR4 = 1), this bit reflects the state of the RTS bit in the MCR (MCR1).
Bit 3 Delta Data Carrier Detect (DDCD)
This bit is set to a 1 when the DCD bit changes state since the host last read the MSR.
Bit 2 Trailing Edge of Ring Indicator (TERI)
This bit is set to a 1 when the RI bit changes from a 1 to a 0 state since the host last read the MSR.
Bit 1 Delta Data Set Ready (DDSR)
This bit is set to a 1 when the DSR bit has changed since the host last read the MSR.
Bit 0 Delta Clear to Send (DCTS)
This bit is set to a 1 when the CTS bit has changed since the MSR the host last read the MSR.
RBX – RX Buffer (Receiver Buffer Register)
(Addr = 0, DLAB = 0)
The RX Buffer (RBR) is a read-only register at location 0 (with DLAB = 0). Bit 0 is the least significant bit of the data and is the first bit received.
THR – TX Buffer (Transmitter Holding Register)
(Addr = 0, DLAB = 0)
The TX Buffer (THR) is a write-only register at address 0 when DLAB = 0. Bit 0 is the least significant bit and the first bit sent.

Introduction
Multi-Tech’s SocketModem creates communication-ready devices by integrating data/fax/voice functionality into a single product design. The SocketModem is a space-efficient (1" × 2.5"), embedded modem that provides V.92/56K communication. The complete, ready-to-integrate modem dramatically reduces development time and costs for system designers.
The MT5634SMI SocketModem is used for integrating data and fax communications:
• It is a single-port modem, which integrates the controller, DSP, and DAA in a 1" x 2.5" form factor and
communicates to a host controller via an asynchronous serial interface
• It is available with an 8-bit parallel interface

SocketModem Parallel Interface Internal Registers
The SocketModem parallel interface is a mimic of a 16C550A UART. It is similar to the MIMIC interface used in the Zilog Z80189. The SocketModem mimic (MMM) takes advantage of this standard interface while replacing the serial to parallel data transfer with a less complicated parallel to parallel data transfer.
The MMM interface controls an 8-bit parallel data transfer which is typically interrupt driven. Interrupts usually indicate one or both of two conditions: (1) the receive (RX) FIFO has either reached a trigger level or time-out condition and needs to be emptied and/or (2) the transmit (TX) FIFO is empty and waiting for more data from the Host. An interrupt can also be triggered by a change in the modem status register (i.e., loss of carrier) or by the occurrence of errors in the line status register (overrun, parity, framing, break detect).
In addition to the receive and transmit FIFOs, there are twelve other control/status registers called the MMM register set which can be accessed through this interface.
Overview
SocketModem MIMIC (MMM) Operation
Data flow through MMM is bi-directional. Simultaneously, data can flow from the host through the transmit FIFO to the SocketModem controller, and data can flow from SocketModem controller through the receive FIFO to the Host. In the receive path, 8-bit data is asynchronously received (from the SocketModem controller) by the receive FIFO where it is stored along with associated three error bits. The error bits must arrive (via a SocketModem controller I/O write to MMM shadow line status register) prior to receiving the actual data bits. The error bits are then temporarily stored so they may be written, with associated data bits, to the 11-bit wide RX FIFO.
After every data write, the RX FIFO write pointer is incremented. RX FIFO trigger levels, data ready signal, and time­out counter are checked to see if a Host interrupt needs to be sent. The data ready signal will be activated and MMM sits poised to accept another data word.
We highly recommend the host should read the MMM IIR register to determine the type of interrupt. Then it might check bit 7 of the LSR to see if there are any errors in the data currently residing in the receive FIFO. Finally, it will (1) alternately read a data word through the RX FIFO read pointer and the error bits via the MMM LSR until the FIFO is empty, or (2) read successive data words (knowing there were no errors in the FIFO) until the trigger count is met.
A similar sequence occurs when data flows in the other direction (from host through transmit FIFO), except there is no error bit manipulation/checking involved.
FIFO Operation
The 16-byte transmit and receive data FIFOs are enabled by the FIFO Control Register (FCR) bit-0. You can set the receive trigger level via FCR bits 6/7. The receiver FIFO section includes a time-out function to ensure data is delivered to the external host. An interrupt is generated whenever the Receive Holding Register (RHR) has not been read following the loading of a character or the receive trigger level has been reached.
Receive (RX) FIFO
The RX FIFO can be configured to be 16 words deep and 11 bits wide. Each word in the RX FIFO consists of 8 data bits and 3 error bits. The RX block of the MMM contains read and write pointers and status flag circuitry that need only to be presented with data (for input), reset, read/write control signals, and read/write clock signals. The RX block of the MMM internally manages the FIFO register file and pointers, and it provides simultaneous read/write capability (no contention problems).
The RX block of the MMM provides data (for output), FIFO full flag, FIFO empty flag, and an almost full flag which uses an associated predefined trigger level (obtained from the MMM FCR control register) to signal when the trigger level has been met. Four possible trigger levels may be selected by programming bits 6-7 of the FCR control register.
Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342D) 72
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92)
A typical (interrupt driven) write to the RX block is a two-step process. The MMM micro-controller must first write the 3 error bits to a shadow MMM LSR status register. Next, the micro-controller writes the data to the RX FIFO and during this write operation, the 3 error bits are directly loaded from the LSR shadow register into the bits 8­10 of the selected (11 bit-wide) FIFO register. These error bits represent the parity error, framing error, and break interrupt signals associated with each data work transmission into the receive FIFO. When the receive FIFO is read, these error bits are loaded directly into bits 2-4 of the MMM LSR register.

Time Out Interrupts
The interrupts are enabled by IER bits 0-3. Care must be taken when handling these interrupts. Following a reset the transmitter interrupt is enabled, the SocketModem will issue an interrupt to indicate that transmit holding register is empty. This interrupt must be serviced prior to continuing operations.
The LSR register provides the current singular highest priority interrupt only. A condition can exist where a higher priority interrupt may mask the lower priority interrupt(s). Only after servicing the higher pending interrupt will the lower priority interrupt(s) be reflected in the status register. Servicing the interrupt without investigating further interrupt conditions can result in data errors. When two interrupt conditions have the same priority, it is important to service these interrupts correctly.
Receive Data Ready and Receive Time Out have the same interrupt priority (when enabled by IER bit-3). The receiver issues an interrupt after the number of characters received have reached the programmed trigger level. In this case the MMM FIFO may hold more characters than the programmed trigger level. Following the removal of a data byte, the user should recheck LSR bit-0 for additional characters. A Receive Time Out will not occur if the receive FIFO is empty. The time out counter is reset at the center of each stop bit received or each time the receive holding register (RHR) is read.

RBR – Receive Buffer (RX FIFO)
All eight bits are used for receive channel data (host read/data in; host write/data out). The three error bits per byte are copied into bits 2, 3, and 4 of the LSR during each host I/O read; therefore, they are available for monitoring on a per-byte basis.
THR – Transmit Holding Register (TX FIFO)
All eight bits are used for transmit channel data (host write/data out; host read/data in).
IER – Interrupt Enable
Bits 4–7: Reserved and will always read 0.
Bits 0-3: Set by host software only and cleared by software control or host reset.
Bit 3: Enables modem status IRQ. If bits 0–3 of the MSR are set and this bit is set to 1 (enabled),
a host interrupt is generated.
Bit 2: Enables receive line status IRQ. If bits 1–4 (overrun, parity, framing, break errors) of the
LSR are set and this bit is set to a logic 1, a host interrupt is generated.
Bit 1: Enables transmit holding register IRQ. If bit 5 (transmit holding register empty) of the LSR is
set and this bit is set to a 1, a host interrupt is generated.
Bit 0: Enables received data available IRQ. If bit 0 (data ready) of the LSR is set and this bit is set
to a 1, a host interrupt is generated.
IIR – Interrupt Identification (Read Only)
Bits 6–7: (FIFO enabled bits). These bits will read a 1 if FIFO mode is enabled and the 16450 enable
bit is 0 (no force of 16450 mode).
Bits 4–5: Reserved and always read a 0.
Bits 1–3: Interrupt ID bits.
Bit 0: Interrupt pending. If logic 0 (in default mode), an interrupt is pending.
When the host accesses IIR, the contents of the register are frozen. Any new interrupts will be recorded, but not acknowledged during the IIR access. This requires buffering bits (0–3, 6–7) during IIR reads.

Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92)
FCR – FIFO Control
Bits 6–7: Used to determine RX FIFO trigger levels. Bit 5: Used to detect a change in the FCR. Bit 4: TX FIFO overrun bit. Bit 3: DMA mode select. If bit 3 is a 0, the 16450 mode is enabled which does only single-byte
transfers. When bit 3 is a 1, it enables a multiple byte (FIFO mode) data transfer.
Bit 2: TX FIFO reset. This will cause TX FIFO pointer logic to be reset (any data in TX FIFO will be
lost). This bit is self clearing; however, a shadow bit exists that is cleared only when read by the host, thus allowing the host to monitor a FIFO reset.
Bit 1: RX FIFO reset. This will cause RX FIFO pointer logic to be reset (any data in RX FIFO will
be lost). This bit is self clearing; however, a shadow bit exists that is cleared only when read by the host, thus allowing the host to monitor a FIFO reset.
Bit 0: FIFO enable. The host writes this bit to logic 1 to put the block in FIFO mode. This bit must
be a 1 when writing other bits in this register or they will not be programmed. When this bit changes state, any data in the FIFOs or the RBR and THR registers will be lost and any pending interrupts are cleared.
Bit 7 Bit 6 16 Deep FIFO Trigger Levels (# of bytes) Default
0 0 1 0 1 4 1 0 8 1 1 14
LCR – Line Control
Bit 7: Divisor latch access bit. This bit allows the host, access to the divisor latch. Under
normal circumstances, the bit is set to 0 (provides access to the RX and TX FIFOs at address 0). If the bit is set to 1, access to transmitter, receiver, interrupt enable, and modem control registers is disabled. In this case, when an access is made to address 0, the divisor latch least (DLL) significant byte is accessed. Address 1 accesses the most significant byte (DLM). Address 7 accesses the DLX divisor latch register. Address 4 accesses the MCX status/control register.
Bit 6: Used to denote a host-generated set break condition. Bits 0,1,3,4,5: Used only in parity bit generation for the 7 bit data byte case. Bits 0 and 1 are used for
word length select (b0 = 0 and b1 = 1 is used for 7 bit data). Bit 3 is parity enable. Bit 4 is even parity select. Bit 5 is stick parity.
MCR – Modem Control
Bits 5–7: Reserved, and will always be 0. Bit 4: Used for loopback. When a 1, bits 0–3 of the MCR are reflected in modem status register
(MSR) as follows: RI <= OUT1, DCD <= OUT2, DSR <= DTR, CTS <= RTS. Emulation of loopback feature of 16550 UART must be done by the host except for the above conditions. Also, when this bit is set, it allows for data loop back. This means the host can write a data word to the TX and immediately read back the same data word from the RX (in a manner similar to the 16550A).
Bit 3: Controls the signal used to 3-state the host interrupt. If 0, then an active-low L33xV output
will be set to 0, and this signal will be used to 3-state the host interrupt output pin.
Bits 0–2: Used during LOOP function. Bit 2: OUT1. Bit 1: Request to Send (RTS). Bit 0: Data terminal ready (DTR).
Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342D) 76
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92)
LSR – Line Status
Bit 7: Error in RX FIFO. This bit is always set to 1 if at least one data byte in the RX FIFO has an
error. This will clear when there are no more errors in the RX FIFO.
Bit 6: Transmitter empty. This bit is the same as LSR bit 5 (THRE) in MMM
Bit 5: Transmitter holding register empty. This bit is set to 1 when either the transmitter holding
register has been read (emptied) by the micro-controller (16450 mode) or the TX FIFO is empty (16550 mode). This bit is set to 0 when either the THR or the TX FIFO becomes not empty in 16450 mode. In 16550 mode, it is set to 0 only after the trigger level has been met since the last occurrence of TX FIFO empty. If the transmitter timer is enabled, a shadow bit exists which delays the timer setting this bit to 1. When reading this bit, the micro-controller will not see the delay. Both shadow and register bits are cleared when the host writes to the THR or TX FIFO in 16450 mode. The trigger level must be reached to clear the bit in 16550 (FIFO) mode.
Bits 2–4: Used for parity error, framing error, and break detect. These bits are written, indirectly, by the
micro-controller as follows: The bits are first written to the shadow bit locations when the micro­controller write accesses the LSR. When the next character is written to the receive buffer (RBR) or the RX FIFO, the data in the shadow bits is then copied to the RBR (16450 mode) or RX FIFO (16550 mode). In FIFO mode, bits become available to the host when the data byte associated with the bits is next to be read. In FIFO mode, with successive reads of the receiver, the status bits will be set if an error occurs on any byte. Once the micro-controller writes to the RBR or RX FIFO, the shadow bits are auto cleared. The register bits are updated with each host read.
Bit 1: Overrun error. This bit is set if the micro-controller makes a second write to RBR before the
host reads data in the buffer (16450 mode) or with a full RX FIFO (16550 mode). No data will be transferred to the RX FIFO under these circumstances. This bit is reset when the host reads the LSR.
Bit 0: Data ready bit. This bit is set to 1 when received data is available, either in the RX FIFO
(16550 mode) or the RBR (16450 mode). This bit is set immediately upon the micro-controller writing data to the RBR or FIFO if the receive timer is not enabled, but it is delayed by the timer interval if the receive timer is enabled. For micro-controller read access, a shadow bit exists so that the micro-controller does not see the delay that the host sees. Both bits are cleared to logic 0 immediately upon reading all data in either RBR or RX FIFO.
MSR – Modem Status
Bits 4 through 7 of the MSR can also take on the MCR bits 0 through 3 value when in MCR loop mode (i.e. when MCR b4 = 1). The transfer of bits in loop back has a null modem twist (i.e. MCR b0 goes to MSR b5 and MCR b1goes to MSR b4).
Bit 7: Data carrier detect (DCD) bit.
Bit 6: Ring indicator (RI) bit.
Bit 5: Data set ready (DSR) bit.
Bit 4: Clear to send (CTS) bit.
Bit 3: Delta data carrier detect pin. This bit is set to a 1 whenever the data carrier detect bit changes
state. It is reset when the host reads the modem status register.
Bit 2: Trailing edge ring indicator bit. This bit is set to 1 on the falling edge of the ring indicator bit. It
is reset when the host reads the modem status register.
Bit 1: Delta data set ready bit. This bit is set to 1 whenever the data set ready changes state. It is
reset when the host reads the modem status register.
Bit 0: Delta clear to send bit. This bit is a one whenever the clear to send bit changes state. It is reset
when the host reads the modem status register.

SCR – Scratch
The host programmer uses this register for temporary data storage.
DLL – Divisor Latch (LSByte)
This register contains low-order byte for the 16-bit clock divider. It is kept to maintain register set compatibility with the 16C550A interface. However, it is not used for clock generation since MMM does not require the generation of a real baud clock.
DLM – Divisor Latch (MSByte)
This register contains high-order byte for the 16-bit clock divider. It is kept to maintain register set compatibility with the 16C550A interface. However, it is not used for clock generation, since MMM does not require the generation of a real baud clock.
Programming the Baud Rate Generator Registers DLM (MSB) and DLL (LSB) provides a user capability for selecting the desired final baud rate. The example in the Table below shows the selectable baud rates available when using a 1.8432 MHz external clock input.

Introduction
The Multi-Tech SocketModem IP integrates dial-up PSTN modem functionality and a complete TCP/IP protocol stack into a single product design.
The SocketModem IP is a complete ready-to-integrate module that embeds Internet protocols inside your product device allowing it to send and receive data over the Internet without connecting to a PC or gateway server.
The space efficient (1” x 2.5”) embedded modem of the SocketModem IP sends and receives data via e-mail, HTTP, or socket interfaces.
The SocketModem IP has successfully completed international compliance testing (homologation) for global approval. This means you can specify one module for each system used across the world. And, since the SocketModem IP is a host independent device, the associated telecom approvals are portable across any solution for which it is integrated.
