Throughout this manual, a convention is used which precedes data and address parameters by a character identifying the numeric format as follows:

$ dollar specifies a hexadecimal character % percent specifies a binary number & ampersand specifies a decimal number

Unless otherwise specified, all address references are in hexadecimal.

An asterisk (*) following the signal name for signals which are level-significant denotes that the signal is true or valid when the signal is low.

An asterisk (*) following the signal name for signals which are edge-significant denotes that the actions initiated by that signal occur on high-to-low transition.

In this manual, assertion and negation are used to specify forcing a signal to a particular state. In particular, assertion and assert refer to a signal that is active or true; negation and negate indicate a signal that is inactive or false. These terms are used independently of the voltage level (high or low) that they represent.

Data and address sizes are defined as follows:

A byte is eight bits, numbered 0 through 7, with bit 0 being the least significant. A half word is 16 bits, numbered 0 through 15, with bit 0 being the least significant. A word is 32 bits, numbered 0 through 31, with bit 0 being the least significant. A double word is 64 bits, numbered 0 through 63, with bit 0 being the least

significant.

Unpacking Instructions

Note If the shipping carton is damaged upon receipt, request

that the carrier’ s agent be present during the unpacking and inspection of the equipment.

Unpack the equipment from the shipping carton. Refer to the packing list and verify that all items are present. Save the packing material for storing and reshipping of equipment.

Caution

Avoid touching areas of integrated circuitry; static discharge can damage circuits.

Hardware Configuration

To produce the desired configuration and ensure proper operation of the MVME1603/1604, you may need to carry out certain modifications before installing the module.

The MVME1603/1604 provides software control ove r most options: by setting bits in control registers after installing the MVME1603/ 1604 in a system, you can modify its configuration. (The MVME1603/1604 control registers are described in Chapter 3, and/or in the MVME1603/MVME1604 Single Board Computer Programmer’s Reference Guide as listed under Related Documentation in Appendix A.)

Some options, however, are not software-programmable. Such options are controlled through manual installation or removal of header jumpers or interface modules on the base board or the associated modules.

Hardware Preparation and Installation

MVME1600-001 Base Board Preparation

Figure 1-3 illustrates the placement of the switches, jumper headers, connectors, and LED indicators on the MVME1600-001. Manually configurable items on the base board include:

❏ SCSI bus terminator selection (J7) ❏ General-purpose software-readable header (J8) ❏ VMEbus system controller selection (J9) ❏ Serial Port 3 clock configuration (J10) ❏ Serial Port 4 clock configuration (J13)

Serial ports on the associated MVME760 transition module are also manually configurable. For a discussion of the configurable items

on the transition module, refer to the user’s manual for the MVME760 (part number VME760UA) as necessary.

The MVME1600-001 has been factory tested and is shipped wit h the configurations described in the following sections. The MVME1600-001’s required and factory-installed Debug Monitor, PPCBug, operates with those factory settings.

SCSI Bus Terminator Selection (J7)

The MVME1600-001 provides terminators for the SCSI bus. The SCSI terminators are enabled or disabled by a jumper on h eader J7. The SCSI terminators may be configured as follows.

General-Purpose Software-Readable Header (J8)

Header J8 provides eight readable jumpers. These jumpers can be read as a register at ISA I/O address $80000801. Bit 0 is associated with header pins 1 and 2; bit 7 is associated with pins 15 and 16. The bit values are read as a zero when the jumper is installed, and as a one when the jumper is removed. The PowerPC firmware (PPCBug) reserves the four lower-order bits, SRH3 to SRH0. They are defined as shown in the list below:

Low-Order Bit Pins Definition Bit #0 (SRH0) 1—2 Reserved for future use.

Bit #1 (SRH1) 3—4 With the jumper installed between pins 3 and 4

(factory configuration), the debugger uses the current user setup/operation parameters in NVRAM. When the jumper is removed (making the bit a 1), the debugger uses the default setup/operation parameters in ROM instead. Refer to the ENV command

description in Chapter 6 for the ROM defaults. Bit #2 (SRH2) 5—6 Reserved for future use. Bit #3 (SRH3) 7—8 Reserved for future use.

1-8

The four higher-order bits, SRH4 to SRH7, are user-definable. They can be allocated as necessary to specific applications. The MVME1600-001 is shipped from the factory with J8 set to all zeros (jumpers on all pins).

Console Port Configuration

On the MVME1600-001 base board, either the standard serial console port ( the PPCBug firmware console port.

The firmware checks for the presence of a connected k eyboard and a connected mouse. If either device is connected to the PowerPC system and a firmware-supported video card/video device is found, the firmware is automatically brought up on the connected video terminal. If neither a mouse nor keyboard is connected, the firmware is brought up on the serial port ( up on the serial port (

however, the firmware will display a “Keyboard not connected” message. In order to use the firmware, you must then plug the keyboard in.

Conversely, if you remove the VGA monitor, also remove the keyboard and mouse to avoid unexpected behavior by the firmware.

1-9

Page 18

MVME1600-001 Base Board Preparation

If you plan to use a terminal other than a VGA device as the firmware console, set it up as follows:

❏ Eight bits per character ❏ One stop bit per character ❏ Parity disabled (no parity) ❏ Baud rate of 9600 baud

9600 baud is the power-up default for serial ports on MVME1603/ 1604 boards. After power-up you can reconfigure the baud rate if

you wish, via the PPCBug firmware’s Port Format (PF) command. Whatever the baud rate, the terminal must perform some type of hardware handshaking — either XON/OFF or via the CTS line.

VMEbus System Controller Selection (J9)

The MVME1600-001 is factory-configured in system controller mode (i.e., a jumper is installed across pins 2 and 3 of header J9). This means that the MVME1600-001 assumes the role of system controller at system power-up or reset.

1-10

Leave the jumper installed across pins 2 and 3 if you intend to operate the MVME1600-001 as system controller in all cases.

Remove the jumper from J9 if the MVME16 00- 001 i s n ot to ope ra te as system controller under any circumstances.

Note that when the MVME1600-001 is functioning as system controller, the

Serial Port 3 Clock Configuration (J10)

You can configure Serial port 3 on the MVME1600-001 to use the clock signals provided by the TXC signal line. Header J10 configures port 3 to either drive or receive TXC. The factory configuration has port 3 set to receive TXC.

To complete the configuration of the TXC clock line, you must also set serial port 3 clock configuration header J9 on the MVME760 transition module, described later in this chapter. For details on the configuration of that header, refer to the MVME760 Transition

Module section or to the user’s manual for the MVME760 (part number VME760UA).

Serial Port 4 Clock Configuration (J13)

You can configure Serial port 4 on the MVME1600-001 to use the clock signals provided by the TXC signal line. Header J13 configures port 4 to either drive or receive TXC. The factory configuration has port 4 set to receive TXC.

To complete the configuration of the TXC clock line, you must also set serial port 4 clock configuration header J8 on the MVME760 transition module (described later in this chapter). For details on the configuration of that header, refer to the MVME760 Transition

Module section or to the user’s manual for the MVME760 (part number VME760UA).

Remote Status and Control

The MVME1600-001 front panel LEDs and switches are mounted on a removable mezzanine board. Removing the LED mezzanine makes the mezzanine connector (J1, a keyed double-row 14-pin connector) available for service as a remote status and control connector. This allows a system designer to construct a RESET/LED panel that can be located apart from the MVME1600-

001. Maximum cable length is 15 feet. In this application, J1 can be connected to a user-supplied external

cable to carry the signals for remote reset, abort, the LEDs, and a general-purpose I/O signal. The I/O signal is a general-purpose interrupt pin which can also function as a trigger input. The interrupt pin is level programmable.

MVME760 Transition Module Preparation

The MVME760 transition module (Figure 1-4) is used in conjunction with the MVME1600-001 base board. The features of the MVME760 include:

❏ A parallel printer port ❏ An Ethernet interface supporting both AUI and 10BaseT

connections

❏ Two EIA-232-D asynchronous serial ports (identi fied as COM1

COM2 on the front panel)

and

❏ Two synchronous serial ports (ports 3 and 4)

Configuration of Serial Ports 3 and 4

The synchronous serial ports, Serial Port 3 and Serial Port 4, are configurable via a combination of serial interface modules (SIMs) and jumper settings. The following table lists the synchronous serial ports with their corresponding SIM connectors and jumper headers.

MVME1600-011 Base Board Preparation

Figure 1-5 illustrates the placement of the switches, jumper headers, connectors, and LED indicators on the MVME1600-011. Manually configurable items on the base board include:

❏ Serial Port 4 DCE/DTE selection (J7) ❏ Serial Port 4 clock selection (J8, J15, J16) ❏ Serial Port 4 I/O path selection (J9) ❏ VMEbus system controller selection (J10) ❏ Serial Port 3 I/O path selection (J13) ❏ General-purpose software-readable header (J14)

Serial ports on the associated MVME712M transition module are also manually configurable. For a discussion of the configurable

items on the transition module, refer to the user’s manual for the MVME712M (part number MVME712M) as necessary. The MVME1600-011 has been factory tested and is shipped with the configurations described in the following sections. The required and factory-installed Debug Monitor, PPCBug, operates with those factory settings.

Serial Port 4 DCE/DTE Selection (J7)

Serial port 4 on the MVME1600-011 is DCE/DTE configurable. Header J7 sets a configuration bit for serial port 4 in the Z8536 ID register. Software reads the bit as either a DCE or DTE value and configures the port accordingly. Header J7 may be configured as follows.

Jumper Off = DCE in ID Register

Serial Port 4 Clock Selection (J8/15/16)

The MVME1600-011 is shipped from the factory with Serial Port 4 configured for asynchronous communications (i.e., the internal clock is used). Port 4 can be configured for synchronous communications as well. It can either drive (using the internal clock) or receive (using an external clock) the Re ceive and Transmit clock signals. To select synchronous communications for the Serial Port 4 connection, install jumpe rs on headers J 8, J15, a nd J16 in one of the configurations shown below.

Hardware Preparation and Installation

To complete the configuration of the clock lines, you must also set serial port 4 clock configuration header J15 on the MVME712M transition module (described later in this chapter). For details on the configuration of that header, refer to the MVME712M Transition

Module section or to the user’s manual for the MVME712M (part number MVME712M).

Serial Port 4 I/O Path Selection (J9)

On the MVME1600-011, serial port 4’s I/O signals are routed to backplane connector P2 and to front panel connector J3. Header J9 determines the state of the DSR, RI, and TM signals on serial port 4.

With a jumper installed on J9, DSR, RI, and TM come from the front panel.

With the jumper removed, P2 I/O is selected. The DSR, RI, and TM signals are not supported in this case, so DSR is held true while RI and TM are held false.

VMEbus System Controller Selection (J10)

The MVME1600-011 is factory-configured in system controller mode (i.e., a jumper is installed across pins 2 and 3 of header J10). This means that the MVME1600-011 assumes the role of system controller at system power-up or reset.

Leave the jumper installed across pins 2 and 3 if you intend to operate the MVME1600-011 as system controller in all cases.

Remove the jumper from J10 if the MVME1600- 011 is not to operate as system controller under any circumstances.

Note that when the MVME1600-011 is functioning as system controller, the

SYS LED is turned on.

Serial Port 3 I/O Path Selection (J13)

On the MVME1600-011, serial port 3’s I/O signals are routed to backplane connector P2 and to front panel connector J2. Header J13 determines the state of the DSR, RI, and TM signals on serial port 3.

With a jumper installed on J13, DSR, RI, and TM come from the front panel.

With the jumper removed, P2 I/O is selected. The DSR, RI, and TM signals are not supported in this case, so DSR is held true while RI and TM are held false.

General-Purpose Software-Readable Header (J14)

Header J14 provides eight readable jumpers. These j umpers ca n be read as a register at ISA I/O address $80000801. Bit 0 is associated with header pins 1 and 2; bit 7 is associated with pins 15 and 16. The bit values are read as a zero when the jumper is installed, and as a one when the jumper is removed.

The PowerPC firmware (PPCBug) reserves the four lower-order bits, SRH3 to SRH0. They are defined as shown in the following list:

Remote Status and Control

The remote status and control connector, J4, is a keyed double-row 20-pin connector located behind the front panel of the MVME1600 -

011. It connects to a user-supplied external cable and carries the signals for remote reset, abort, the LEDs, and three general-purpose I/O signals. This allows a system designer to construct a RESET/LED panel that can be located remotely from the MVME1600-011. This feature is similar to the remote connector provided on the MVME167 and MVME187 Single Board Computers; maximum cable length is 15 feet.

The general-purpose I/O signals include two TTL-level I/O pins and one general-purpose interrupt pin which can also function as a trigger input. The interrupt pin is level programmable.

Table 1-3 lists the pin numbers, signal mnemonics, and signal descriptions for J4.

Hardware Installation

The following sections discuss the placement of the various mezzanine cards on the the MVME1600-001 and the MVME1600011 base boards, the installation of the complete MVME1603/1604 VMEmodule assembly and corresponding transition module into a VME chassis, and the system considerations relevant to the installation. Before installi ng the MVME1603/1604 , ensure that the serial ports and all header jumpers are configured as desired.

In most cases, the mezzanine cards—the processor/memory module, the LED mezzanine, the DRAM module, and (if applicable) the optional PCI mezzanine—are already in place on the MVME1603/1604. The user-configura ble jumpers are accessible with the mezzanines installed.

Should it be necessary to install mezz anines on the base board, refer to the following sections for a brief description of the installation procedure. If necessary, you can find additional information in the user’s manuals for the individual mezzanine cards.

ESD Precautions

Use ESD

Wrist Strap

1-32

Motorola strongly recommends that you use an antistatic wrist strap and a conductive foam pad when installing or upgrading a system. Electronic components, such as disk drives, computer boards, and memory modules, can be extremely sensitive to ESD. After removing the component from the system or its protective wrapper, place the component flat on a grounded, static-free surface (and in the case of a board, component side up). Do not slide the component over any surface.

If an ESD station is not available, you c an avoid damage resulting from ESD by wearing an antistatic wrist strap (available at electroni cs stores) that is attached to an unpainted metal part of the system chassis.

System Considerations

The MVME1603/1604 draws power from VMEbus backplane connectors P1 and P2. P2 is also used for the upper 16 bits of data in 32-bit transfers, and for the upper 8 address lines in extended addressing mode. The MVME1603/1604 may not function properly without its main board connected to VMEbus backplane connectors P1 and P2.

Whether the MVME1603/1604 operates as a VMEbus master or as a VMEbus slave, it is configured fo r 32 bits of address and 32 b its of data (A32/D32). However, it handles A16 or A24 devices in the address ranges indicated in Chapter 2. D8 and/or D16 devices in

the system must be handled by the PowerPC™ processor software. Refer to the memory maps in Chapter 2.

The MVME1603/1604 contains shared onboard DRAM (and, optionally, secondary cache memory) whose base address is software-selectable. Both the onboard processor and offboard VMEbus devices see this local DRAM at base physical address $00000000, as programmed by the PPCBug firmware. This may be changed via software to any other base address. Refer to the

MVME1603/MVME1604 Single Board Computer Programmer’s Reference Guide for more information.

Hardware Preparation and Installation

If the MVME1603/1604 tries to access offboard resources in a nonexistent location and is not system controller, and if the system does not have a global bus timeout, the MVME1603/1604 waits forever for the VMEbus cycle to complete. This will cause the system to lock up. There is only one situation in which the system might lack this global bus timeout: when the MVME1603/1604 is not the system controller and there is no global bus timeout elsewhere in the system.

Multiple MVME1603/1604s may be installed in a single VME chassis. In general, hardware multiprocessor features are supported.

1-45

Page 54

System Considerations

Note If you are installing multiple MVME1603/1604s in an

MVME945 chassis, do not install an MVME1603/1604 in slot 12. The extra thickness of the module may cause clearance difficulties in that slot position.

Other MPUs on the VMEbus can interrupt, disable, communicate with, and determine the operational status of the processor(s). One register of the GCSR (global control/status register) set includes four bits that function as location monitors to allow one MVME1603/1604 processor to broadcast a signal to any other MVME1603/1604 processors. All eight registers are accessib le from any local processor as well as from the VMEbus.

The MVME1600-001 and MVME1600-011 base boards draw +5Vdc,

+12Vdc, and –12Vdc power from the VMEbus backplane through connectors P1 and P2. The 3.3Vdc power (used by the ISA Super I/O device on the base board, and by the PM603 or PM604 processor/memory mezzanine) is derived on-board from the +5Vdc.

MVME1600-001 Base Board

The MVME1600-001 base board furnishes +12Vdc, –12Vdc, and +5Vdc power to the MVME760 transition module through polyswitches (resettable fuses) F4, F2, and F3. The MVME760 uses these voltage sources to power the serial port drivers and any LAN transceivers connected to the transition module. The on the MVME1600-001 front panel illuminates when all three voltages are available.

The fused +5Vdc power is also supplied to the base board’s keyboard and mouse connectors and to the 14-pin combined LEDmezzanine/remote-reset connector, J1.

Note Because any device on the SCSI bus can provide

TERMPWR, and because the FUS LED monitors the status

of several voltages, the LED does not directly indicate the condition of any single fuse. If the LED flickers or goes out, check all the fuses (polyswitches).

The MVME1600-001 base boa rd supplies a the 14-pin combined LED-mezzanine/remote-reset connector, J1. When J1 is used as a remote reset connector with the LED mezzanine removed, the external speaker. For the pin assignments of J1, refer to Table 1-2.

MVME1600-011 Base Board

The MVME1600-011 base board provides +5Vdc power to the remote LED/switch connector (J4) through a 1A fuse (F1) located between P1 and P2. (J4 provides a separate connection point for a remote control and indicator panel, making it unnecessary to share the LED mezzanine connector for that purpose.)

System Considerations

The MVME1600-011 base board supplies SCSI terminator power through a 1A fuse (F1) located on the P2 adapter board. I f the fu se is blown, the SCSI device(s) may function erratically or not at all. With the P2 adapter board cabled to an MVME712M and with an SCSI bus connected to the MVME712M, the green DS2 LED on the MVME712M illuminates when SCSI terminator power is avai lable. If the DS2 LED flickers during SCSI bus operation, check fuse F1 on the P2 adapter board.

Like the MVME1600-001 base board, the MVME1600-011 supplies a

SPEAKER_OUT signal to the 14-pin LED mezzanine connector, J1.

Unlike the MVME1600-001 base board, the MVME1600-011 also applies the control connector, J4. The LED mezzanine need not be removed to cable the assignments of J4, refer to Table 1-3.

Block Diagram

As shown in the Features section, The MVME1603/MVME1604

offers many standard features desirable in a computer system— such as synchronous and asynchronous serial ports, parallel port,

boot ROM and DRAM, SCSI, Ethernet, provision for a disk drive mezzanine, and (MVME1600-001 base board only) keyboard, mouse, and graphics support—in a one- or two-slot VME package. Its flexible mezzanine architecture allows relatively easy upgrades of the processor and/or memory.

A key feature of the MVME1603/MVME1604 family is the PCI (Peripheral Component Interconnect) bus. In addition to the onboard local bus peripherals, the PCI bus supports an industrystandard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card).

PMC modules offer a variety of possibilities for I/O expansion through FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer Mode), graphics, Ethernet, or SCSI ports. Both base boards support PMC front panel I/O.

SCSI Interface

The MVME1603/MVME1604 supports mass storage subsystems

through the industry-standard SCSI bus. These subsystems may include hard and floppy disk drives, streaming tape drives, and other mass storage devices. The SCSI interface is implemented using the NCR 53C825 (on the MVME1600-001 b ase board) or NCR 53C810 (on the MVME1600-011 base board) SCSI I/O controller at a clock speed of 40MHz. The SCSI I/O controller connects directly to the PCI local bus.

The MVME1600-001 base board has an industry-standard 68-pin high-density SCSI connector on the front panel (as illustrated in Figure 1-3).

The MVME1600-011 base board routes its SCSI lines through the P2 connector to the MVME712M transition module (as illustrated in Figure 1-13). The SCSI control lines have filter networks to minimize the effects of VMEbus signal noise at P2.

The SCSI bus is 16 bits wide in MVME1600-001-based versions of the MVME1603/MVME1604, and 8 bits wide in MVME1600-011based versions. Refer to Chapter 4 for the pin assignments of the MVME1600-001 front panel SCSI connector. Refer to the MVME712M User’s Manual for the pin assignments of the transition module SCSI connectors used in the MVME1600-011 SCSI implementation. Refer to the NCR 53C825 and 5 3C810 user’ s guides and the MVME1603/MVME1604 Programmer’s Reference Guide for detailed programming information.

SCSI Termination

The individual configuring the system must ensure that the SCSI bus is properly terminated at both ends.

The MVME1600-001 base board provides onboard SCSI bus termination. The term inators can be enabled or disabled by a

jumper (J7—described in Chapter 1). If the SCSI bus ends at the

3-6

Page 63

Functional Description

MVME1603/MVME1604 module, then SCSI termination must be enabled. +5Vdc power to the SCSI bus termination resistors is supplied through a fuse (F1) and diode.

TERMPWR signal and

The MVME1600-011 base board uses the sockets provided for SCSI bus terminators on the P2 adapter board. If the SCSI bus ends at the adapter board, then termination resistors must be installed on the adapter board. +5Vdc power to the SCSI bus termination resistors is supplied through a fuse located on the adapter board.

Ethernet Interface

The MVME1603/MVME1604 uses Digital Equipment’s DECchip 21040 LAN controller to implement an Ethernet interface that supports both AUI and 10BaseT connections. The balanced differential transceiver lines for AUI and 10BaseT are coupled via on-board transformers.

The MVME1600-001 base board routes its AUI and 10BaseT lines through the P2 connector to the MVME760 transition module (as illustrated in Figure 1-12 on page 1-41). The MVME760 fron t panel has an industry-standard DB15 co nnector and 8-pin RJ45 connector for the AUI and 10BaseT connections respectively (see Figure 1-4 on page 1-17).

The MVME1600-011 base board uses an 8-pin RJ45 on its f ront panel for 10BaseT lines (see Figure 1-5 on page 1-19) and routes its AUI lines through the P2 connector to the MVME712M transition module (as illustrated in Figure 1-13 on page 1-44). The MVME712M front panel has a n industry-s tandard DB 15 c onnector for the AUI connections (see Figure 1-6 on page 1-28).

TERMPWR signal and

Every MVME1603/MVME1604 is assigned an Ethernet station address. The address is $08003E2 xxxx x, where xxx xx i s the unique 5-nibble number assigned to the board (i.e., every board has a different value for xxxxx).

Each MVME1603/MVME1604 displays its Ethernet stati on address on a label attached to backplane connector P2. In addition, the six bytes including the Ethernet station address are stored in the

3-7

Page 64

Block Diagram

NVRAM (BBRAM) configuration area specified by boot ROM. That is, 08003E2xxxxx is stored in NVRAM. At an address of $FFFC1F2C, the upper four bytes (08003E2x) can be read. At an

address of $FFFC1F30, the lower two bytes (xxxx) c an be read. Th e MVME1603/MVME1604 debugger, PPCBug, has the capability to retrieve or set the Ethernet station address.

If the data in the NVRAM is lost, use the number on the label on backplane connector P2 to restore it.

Refer to Chapter 4 for the pin assignments of the MVME1600-011 front panel 10BaseT connector. Refer to the MVME712M User’s Manual for the pin assignments of the transition module AUI connector. Refer to the MVME760 User’s Manual for the pin assignments of the transition module AUI and 10BaseT connectors used in the MVME1600-001 Ethernet implementation. Refer to the BBRAM/TOD Clock memory map description in the MVME1603/MVME1604 Programmer’s Reference Guide for detailed programming information.

Note The MVME1603/MVME1604 will support either AUI or

10BaseT Ethernet connections, but not both at the same time. To switch from one type to the other, do the following:

1. Bring the MVME1603/MVME1604 up in PPCBug.

2. Remove the current Ethernet cable and connect the one you wish to use.

3. Reset the MVME1603/MVME1604 by pressing the

RESET switch or typing the debug command RESET.

The new connection is automatically recognized by the LAN controller.

Graphics Interface

MVME1600-001-based versions of the MVME1603/MVME1604 have a Super VGA (Video Graphics Array) color graphics interface implemented with a Cirrus Logic CL-GD5434 graphics accel erator. The CL-GD5434 supports pixel clock rates of up to 110MHz. Its

3-8

Page 65

Functional Description

internal palette DAC is configur able for industry-stand ard 16- or 256-color VGA modes. The DAC is also extensible to high- and truecolor modes of 32 thousand or 16.7 million colors.

Depending on the color selection and bits-per-pixel mode, the CLGD5434 device supports resolutions of up to 1280 x 1024. 2MB of video buffer memory (in the form of four 256K x 16, 40-pin SOJ, 60ns DRAM chips) are available to the CL-GD5434.

The VGA port routes the graphics data to an industry-standard 3row DB15 connector on the front panel of the MVME1600-001 base board (as illustrated in Figure 1-3).

Refer to Chapter 4 for the pin assignments of the MVME1600-001

front panel VGA connector. Refer to Cirrus Logic’s CL-GD5434 Technical Reference Manual for detailed programming information.

PCI Mezzanine Interface

A key feature of the MVME1603/MVME1604 family is the PCI (Peripheral Component Interconnect) bus. In addition to the onboard local bus devices (SCSI, Ethernet, graphic s, etc.) , the PCI bus supports an industry-standard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card).

The MVME1603/MVME1604 supports one PMC slot. Two 64-pin connectors on the base board (J11 and J12) interface with 32-bit IEEE P1386.1 PMC-compatible mezzanines to add any desirable function. The PCI Mezzanine Card slot has the following characteristics:

Mezzanine Type PMC (PCI Mezzanine Card) Mezzanine Size S1B: Single width, standard depth (75mm x

150mm) with front panel

Page 66

Block Diagram

Refer to Chapter 4 for the pin assignments of the PMC connectors. For detailed programming information, refer to the PCI bus descriptions in the M VME1603/MVME1604 Programmer’s Reference

Guide and to the user documentation for the PMC modules you intend to use.

VMEbus Interface

The VMEchip2 ASIC, in tandem with the VME2PCI ASIC, constitutes the VMEbus interface. The VMEchip2 interfaces an MC68040-style local bus to the VMEbus. The VME2PCI interfaces the PCI bus to an MC68040-style local bus. When the VMEchip2 and the VME2PCI chips are used together, they form a PCI-bus-toVMEbus interface.

The VMEchip2/VME2PCI combination provides:

❏ The local-bus-to-VMEbus interface ❏ The VMEbus-to-local-bus interface ❏ The DMA controller functions of the local VMEbus

The VMEchip2 includes Global Control and Status Registers (GCSRs) for interprocessor communications. It can provide the VMEbus system controller functions as well. For detailed programming information, refer to the VMEchip2 and VME2PCI discussions in the MVME16 03/ MVME1604 Programmer’s Reference Guide.

ISA Super I/O Device (ISASIO)

The MVME1603/MVME1604 uses a PC87303 ISASIO chip from National Semiconductor to implement certain segments of the P2 and front-panel I/O:

❏ Two asynchronous serial ports (COM1 and COM2) via P2

and transition module

❏ IEEE1284 bidirectional parallel port via P2 and transition

module

❏ Disk drive support via drive connector J6 and power

connector J16 (on the MVME1600-001) or J19 (on the MVME1600-011)

❏ Keyboard and mouse interface (MVME1600-001 base board

only)

3-10

Page 67

Asynchronous Serial Ports

The two asynchronous ports provided by the ISASIO device employ TTL-level signals that are routed to the P2 connector. The TTL output lines are buffered through TTL drivers and series resistors. The EIA-232-D drivers and receivers that complete the serial interface are located on the MVME760 (for the MVME1600001 base board) or MVME712M (for the MVME1600-011 base board) transition module.

Hardware initializes the two serial ports as COM1 an d COM2 with ISA I/O base addresses of $3F8 and $2F8 respec tively. This defa ult configuration also assigns COM1 to IBC (ISA/PCI Bridge Controller) interrupt request line IRQ4 and COM2 to IRQ3. You can change the default configuration by reprogramming the ISASIO device. For detailed programming information, refer to the PCI and ISA bus discussions in the MVME1603/MVME1604 Programmer’s Reference Guide and to the vendor documentation for the ISASIO device.

Parallel Port

Functional Description

The parallel port is an IEEE P1284 printer interface implemented with the ISASIO device. All parallel I/O interface signals are routed to P2 through series damping resistors.

Hardware initializes the parallel port as PPT1 with an ISA IO base address of $3BC. This default confi guration also assigns the parall el port to IBC (ISA/PCI Bridge Controller) interrupt request line IRQ7. You can change the default configuration by reprogramming the ISASIO device. For detailed programming informa tion, refer to the PCI and ISA bus discussions in the MVME1603/MVME1604 Programmer’s Reference Guide and to the vendor documentation for the ISASIO device.

3-11

Page 68

Block Diagram

Disk Drive Controller

The ISASIO device incorporates a low- and high-density disk drive controller for use with an optional disk drive. The disk drive may

take the form of a mezzanine board or a separate module. The drive interfaces with the ISASIO controller via base board connector J6. The unit receives power via connector J16 (on the MVME1600-001) or J19 (on the MVME1600-011).

The ISASIO disk drive controller is compatible with the DP8473, 765A, and N82077 devices commonly used to implement floppy disk controllers. Software written for those devices may be used without change to operate the ISASIO controller. The ISASIO device may be used to support any of the following devices:

❏ 3

/2-inch 1.44MB floppy disk drive

❏ 5

/4-inch 1.2MB floppy disk drive

❏ Standard 250kbps to 2Mbps tape drive system

Keyboard and Mouse Interface

On the MVME1600-001 base board, the ISASIO device provides ROM-based keyboard and mouse interface control. The front panel of the MVME1600-001 board has two 6-pin c ircular DIN connectors for keyboard and the mouse connections.

ISA Bridge Controller

The MVME1603/MVME1604 uses an Intel S82378ZB bridge controller to supply the interface between the PCI local bus and the ISA system I/O bus (diagrammed in Figure 1-1 and Figure 1-2 for the two base boards).

3-12

Page 69

Functional Description

The ISA bridge controller provides the following functions:

❏ PCI bus arbitration for:

– The MPC105 (PCI/MPU bus bridge and memory

controller) – The SCSI controller – the Ethernet controller – The VM E2PC I ASIC – The PMC (PCI Mezzanine Card) slot

❏ ISA bus arbitration for DMA devices ❏ ISA interrupt mapping for four PCI interrupts ❏ Interrupt controller functionality to support 14 ISA interrupts ❏ Edge/level control for ISA interrupts ❏ Seven independently programmable DMA channels ❏ One 16-bit timer ❏ Three interval counters/timers

The base address of the configuration space for the ISA bridge controller is at $00800800 in the PCI Configuration area.

Real-Time Clock and NVRAM

The MVME1603/MVME1604 employs an SGS-Thomson surfacemount M48T18 RAM and clock chip to provide 8KB of non-volati le static RAM and a real-time clock. This chip provides a clock, oscillator, crystal, power failure detection, memory write protection, 8KB of NVRAM, and a battery in a package consisting of two parts:

❏ A 28-pin 330mil SO device contai ning the real -time clock, the

oscillator, power failure detection circuitry, 8KB of SRAM, and gold-plated sockets for a SNAPHAT battery

❏ A SNAPHAT battery housing a crystal along with the battery

3-13

Page 70

Block Diagram

The SNAPHAT battery package is mounted on top of the MT48T18 device. The battery housing is keyed to prevent reverse insertion.

The clock furnishes seconds, minutes, hours, day, date, month, and

year in BCD 24-hour format. Corrections for 28-, 29- (leap year), and 30-day months are made automatically . The clock generates no interrupts. Although the M48T18 is an 8-bit device, 8-, 16-, and 32bit accesses from the ISA bus to the M48T18 are supported. Refer to the MVME1603/MVME1604 Pr ogrammer’s Reference Guide and to the M48T18 data sheet for detailed programming and battery life information.

Programmable Timers

Among the resources available to the local processor are a nu mber of programmable timers. Timers are incorporated into the ISA bridge controller, the Z8536 CIO devic e (diagrammed in Figure 1-1 and Figure 1-2 for the two base boards), and the VMEchip2. They can be programmed to generate periodic interrupts to the processor.

Interval Timers

3-14

The ISA bridge controller has three built-in counters that are equivalent to those found in an 82C54 programmable interval timer. These counters are grouped into one timer unit, Timer 1, in the IBC. Each counter output has a specific function:

❏ Counter 0 is associated with interrupt request line IRQ0. It

can be used for system timing functions, such as timer interrupt for a time-of-day.

❏ Counter 1 generates a refresh request signal for ISA memory.

This timer is not used in the MVME1603/MVME1604.

❏ Counter 2 provides the tone for the speaker output function

on the ISA bridge controller (the

SPEAKER_OUT signal which

can be cabled to an external speaker via the remote reset connector).

Page 71

Functional Description

The interval timers use the OSC clock input as their clock source. The MVME1603/MVME1604 module drives the OSC pin with a

14.31818 MHz clock source.

16-Bit Timers

Four 16-bit timers are available on the MVME1603/MVME1604. The ISA bridge controller supplies one 16-bit timer; the Z8536 CIO device provides the other three. For information on programming these timers, refer to the data sheets for the S82378ZB ISA bridge controller and the Z8536 CIO device.

VMEchip2 Timers

Two 32-bit programmable tick timers are available in the optional VMEchip2 ASIC. Refer to the VMEchip2 description in the MVME1603/MVME1604 Programmer’s Reference Guide for detailed programming information.

Note It is advisable to avoid using these timers for system

timing functions, since the VMEchip2 may not be present in all versions of the MVME1603/MVME1604 module.

Serial Communications Interface

The MVME1603/MVME1604 us es a Zilog Z85230 ESCC ( Enhanced Serial Communications Controller) to implement the two synchronous/asynchronous serial communications interfaces, which are routed through P2 for the MVME1600-001 base board and through the front panel for the MVME1600-011 base board. The Z85230 supports synchronous (SDLC/HDLC) and asynchronous protocols. The MVME1603/MVME1604 hardware supports asynchronous serial baud rates of 110B/s to 38.4KB/s.

3-15

Page 72

Block Diagram

Each interface supports the CTS, DCD, RTS, and DTR control signals as well as the TxD and RxD transmit/receive data signals, and TxC/RxC synchronous clock signals. Since not all modem

control lines are available in the Z85230, a Z8536 CIO is used to provide the missing modem lines.

In the MVME1600-001 base board, all modem control lines from t he ESCC are multiplexed/demultiplexed through P2 by a multiplexing function (P2MX, described later in this chapter) due to the pin limitations of the P2 connector.

A PAL device performs decoding of register accesses and pseudo interrupt acknowledge cycles for the Z85230 and the Z8536 in ISA I/O space. The ISA bridge controller supplies DMA support for the Z85230.

The Z85230 receives a 10MHz clock input. The Z85230 supplies an interrupt vector during pseudo interrupt acknowledge cycles. The vector is modified within the Z85230 according to the interrupt source. Interrupt request levels are programmed via the ISA bridge controller. Refer to the Z85230 data sheet and to the MVME1603/ MVME1604 Programmer’s Reference Gu ide for further information.

Z8536 CIO Device

The Z8536 CIO device complements the Z85230 ESCC by supplying signals for Abort interrupt status, fuse status, and SCSI terminator status and control, as well as furnishing modem control lines not provided by the Z85230 ESCC. In addition, the Z8536 CIO device has three independent 16-bit counters/timers.

For MVME1600-001 base boards, the Z8536 CIO device also provides a means of requesting the module ID of the two synchronous/asynchronous serial ports that reside on the MVME760 transition module. Refer to the Z8536 data sheet and to the MVME1603/MVME1604 Programmer’s Reference Guide for further informa tion.

P2 Signal Multiplexing

Due to the limited availability of pins in the P2 backplane

connector, the MVME1600-001 base board multiplexes and demultiplexes certain synchronous I/O control signals that pass between the base board and the MVME760 transition module. This is a hardware function that is entirely transparent to software.

Four signals are involved in the P2 multiplexing function: MXDO, MXDI, MXCLK, and MXSYNC

∗.

MXDO is a time-multiplexed data output line from the main board and MXDI is a time-multiplexed line from the MVME760 module. MXCLK is a 10MHz bit clock for the MXDO and MXDI data lines. MXSYNC

∗ is asserted for one bit time at time slot 15 (refer to the

following table) by the MVME1600-00 1 base board. The MVME760 transition module uses MXSYNC

∗ to synchronize with the base

board.

A 16-to-1 multiplexing scheme is used with MXCLK’s 10MHz bit rate. Sixteen time slots are defined and allocated as follows:

ABORT Switch (S1)

The ABORT switch is located on the LED mezzanine. When acti vated by software, the the base board to the processor at a user-programmable l evel . The interrupt is normally used to abort program execution and return control to the PPCBug debugger firmware located in the MVME1603/1604 EPROM and Flash memory.

RESET Switch (S2)

The RESET switch is located on the LED mezzanine. The RESET

switch resets all onboard devices; it al so drives a the MVME1603/1604 is the system controller. The may be disabled by software.

The VMEchip2 includes both a global and a local reset driver. When the VMEchip2 operates as the VMEbus system controller, the reset driver provides a global s ystem reset by asserting the VMEb us signal

SYSRESET∗. A SYSRESET∗ signal may be generated by the RESET

switch, a power-up reset, a watchdog time out, or by a c ontrol bit in the LCSR in the VMEchip2.

SYSRESET∗ remains asserted for at least

200 ms, as required by the VMEbus specification. Similarly, the VMEchip2 provid es an input signal and a control bi t

to initiate a local reset operation. By setting a control bit, software can maintain a board in a reset state, disabling a fault y board from participating in normal system operation. The local reset driver is enabled even when the VMEchip2 is not the system controller. A local reset may be generated by the a watchdog timeout, a VMEbus

RESET switch, a power-up reset,

SYSRESET∗ signal, or a control bit in

the GCSR.

Note For an MVME1603/1604 without the VMEbus option

(i.e., with no VMEchip2), the LCSR control bit is not available to reset the module. In this case, the watchdog timer is allowed to time out to reset the MVME1603/1604.

Front Panel Indicators (DS1 - DS6)

There are six LEDs on the MVME1603/1604 front panel: CHS, BFL,

CPU, PCI, FUS, and SYS.

❏ CHS (DS1, yellow). Checkstop; driven by the MPC603/604

status lines on the MVME1603/1604. Lights when a halt condition from the processor is detected.

❏ BFL (DS2, yellow). Board Failure; lights when the BRDFAIL∗

signal line is active.

❏ CPU (DS3, green). CPU activity; lights when the DB B∗ (Data

Bus Busy) signal line on the processor bus is active.

❏ PCI (DS4, green). PCI activity; lights when the IRDY∗ (Initiator

Ready) signal line on the PCI bus is active. This indic ates that the PCI mezzanine (if installed) is active.

❏ FUS (DS5, green). Fuse OK; lights when +5Vdc, +12Vdc, and

–12Vdc power is available from the base board to the transition module and remote devices.

Functional Description

Note The circuitry monitored by the

FUS LED differs

between the MVME1600-001 and MVME1600-011 versions of the base board. The differences are detailed under the respective base board descriptions in Chapter 1.

Because the

FUS LED monitors the status of several

voltages on the MVME1600-001, it does not directly indicate the condition of any single fuse. If the LED flickers or goes out, check all the fuses (polyswitches).

PM603/604 Processor/Memory Mezzanine Module

The PM603 or PM604 is the processor/memory mezzanine module that (together with an LED mezzanine, an optional RAM1 04 DRAM module, and an optional PCI mezzanine card) plugs into the MVME1600-001 or MVME1600-011 base boar d to make a compl ete single-board computer. See Figure 1-10.

3-24

You have the choice of a PowerPC603 module (the PM603) or a PowerPC604 module (the PM604) with from 8MB to 64MB of DRAM, or up to 128MB of DRAM with a RAM104. 256KB of L2 cache is available as an opti on. There is no parity or EC C protection on the DRAM.

The PowerPC603 is a 64-bit processor with 16KB or 32KB on-chip cache (8KB/16KB data cache and 8K B/16KB instruction cache). The PowerPC604 is a 64-bit processor with 32 KB on-chip cache (16KB data cache and 16KB instruction cache).

The MPC105 bridge/memory controller located on the processor/memory mezzanine provides the bridge between the PowerPC microprocessor bus and the PCI local bus. The memory is

Page 81

Functional Description

kept on the processor bus to get the optimum performance from the designs. Electrically, the processor/memory module is a PCI connection.

MPC604 boards have double-wide front panels to accommodate a heat sink on the PowerPC604 that protrudes in to the adjacent VM E slot.

The PM603/PM604 module accommodates additional memory. RAM104 modules of 8, 16, 32, or 64MB DRAM are available for memory expansion.

A 192MB memory module is available for the PM604 module as a factory-installed option.

The processor module has sockets for 1MB of Flash memory. The onboard monitor/debugger, PPCBug, resides in the Flash chips. PPCBug provides:

❏ A boot loader and extensive onboard diagnostics ❏ A single-line assembler/disassembler ❏ The capability to save and restore a configuration through

NVRAM

❏ A remote boot capability

Under normal operation, the Flash devices are in “read-only” mode, their contents are pre-defined, and they are protect ed against inadvertent writes due to loss of power conditions. However, for programming purposes, programming voltage is always supplied to the devices and the Flash contents may be modified by executing the proper program command sequence. Refer to the third-party data sheet for further device-specific information and/or to the PFLASH PPCBug command.

The addition of the memory module on the processor/memory module makes a stack three boards high. An MVME1603 SBC maintains a single VME slot width with this stacking, although it does brush the inter-card buffer zone. MVME1604 SBCs have a heatsink on the PowerPC604 that extends well into the adjacent VME slot, so MVME604 boards have double-wide front panels.
