2•3 HARDWARE PREPARATION

To select the desired configuration and ensure proper operation of the MSC8101-ADS board,
changes of the DIP-Switch settings may be required before installation. The location of the
switches, indicators, DIP-Switches, and connectors is illustrated in FIGURE 2-1 "MSC8101-ADS

Top Side Part Location diagram" on page 17. The board has been factory tested and is shipped

with DIP-Switch settings as described in the following paragraphs. Parameters can be changed for
the following conditions:

• The Processor Internal Logic and PLLs Supply Level (1.6V) via potentiometer RP2.

• The Processor I/O Supply Voltage (3.3V) via potentiometer RP1 (be careful since this
power supply feeds another logic devices on the ADS and tool boards).

• The Processor Clocking:

o MODCK(1:3). Determining Core’s and CPM’s PLLs multiplication factor via the

DIP Switch SW9.

o MODCKH(4:6) for the Flash Memory Config. Word/Host Config Word (Power-On

Reset Source Dependent) or from the DIP Switch SW9 for FPGA Config. Setting
(Safe Mode).

o Clock mode update requires power up operation.

• Hard Reset Configuration Word source is selected by the DIP Switch SW9/7.

• Normal (64-bit wide) or Narrow (32-bit wide) Data bus width for Host I/F mode is
selected by the DIP Switches SW5,6.

2•3•1 Setting The Core Supply Voltage Level

The internal Logic & PLL’s of the MSC8101 is powered separately through a supply bus named
1V5. The voltage level over this power bus may vary between 0.9V - 2.1V. In the lower voltage
level, the Processor will operate at lower frequency range, consuming a smaller amount of power
and vice-versa for the higher voltage level.

1V5 power level is factory set for 1.5V, but may be changed by RP2.

2•3•2 Setting MODCK(1:3) For Initial PLLs’ Multiplication Factor - SW9

During Power On reset sequence the Processor samples the three MODCK(1:3) lines which are
driven by Altera FPGA device in accordance with SW9/1-3 setting. MODCK_HI field (MODCK[4–
6]), taken from the reset configuration word, are read from the Flash memory (default value from
Altera FPGA for non-programmed Flash is read from SW9/4-6) or from Host Interface to establish
with the multiplication factors of the CPM’s and Core’s PLLs. SW9 is shown in FIGURE 4-4 "Switch

SW9 MODCK - Description" on page 29:

Some Clock Configuration can see in FIGURE 5-1 on page 43:

2•3•3 Setting HReset Configuration Source

taken from three sources:

1) Flash Memory SIMM.

2) Altera FPGA (Safe Mode).

cale Semiconductor,

Frees

3) Host I/F.

When SW9/7 is OFF, the Hard Reset Configuration Word is taken from Altera FPGA, when it is
ON, the Hard Reset Configuration Word is taken from the Flash SIMM. If SW9/8 (Configuration)
set OFF the Processor will be configured from Host, independent of SW9/7 (Flash Configuration
Enable) position. For correct operation for Host Config. Mode Data bus width will be set to 32-bit
wide.

A. In fact 8 Hard-Reset configuration words are read by a configuration master, however only the first is rel-

evant for a single MSC8101.

4•1 INTRODUCTION

This chapter provides necessary information to use the MSC8101-ADS in host-controlled and
stand-alone configurations. This includes controls and indicators, memory map details, and
software initialization of the board.

4•2 SWITCHES

The MSC8101ADS has the following switches:

4•2•1 Host I/F Setting - SW1

This switch is using for manually set a Host Bus parameters. When Host Configuration is enable
the DIP switch SW1/1-3 will be connected to Data Bus through tri-state buffers and sampled by the
Processor. The SW1 factory set is all ON.

This switch controls lines EE0-EE7,EED, connected to appropriate pins of the Processor. When
Reset Configuration executed, EEs lines, involved in one, are driven by FPGA. In fact, they are
EE0, EE1, EE4 and EE5 which sampled at the rising edge of PORESET~. After configuration is
done level of all EE-signals is set by the switch SW2/1-7. Their status may be read out via

BCSR3/0-6. SW2 is factory set to all ON.

4•2•3 ABORT Switch - SW3

The ABORT switch is normally used to abort program execution, this by issuing a level 0 non­maskable interrupt to the Processor. If the ADS is in stand alone mode, it is the responsibility of
the user to provide means of handling the interrupt, since there is no resident debugger with the
MSC8101-ADS. The ABORT switch signal is denounced, and can not be disabled by software.

4•2•4 SOFT RESET (SRESET) Switch - SW4

The SOFT reset switch SW4 performs Soft Reset to the Processor internal modules, maintaining
it’s configuration (clocks & chip-selects) and SDRAMs’ contents. The switch signal is debounced,
and it is not possible to disable it by software.

4•2•5 DATA Bus Width Setting - SW5 & SW6.

Two switches SW5 & SW6 are using together for preparing the SDRAM Memory Banks for Host
Interface Mode when HDI16 interface is provided over Data Bus lines D32-D63. They should be
set in “32bit” position when DIP-Switch SW9/8 HOST CFG set ON (PPC bus supports Host I/F)
and vice versa - “64bit” when Host I/F disable.

4•2•6 HARD RESET (HRESET) - Switch - SW7

HARD reset is generated when switch SW7 is pressed. When the Processor executes HARD reset
sequence, all its configuration is lost, including data stored in the SDRAMs and the Processor has

to be re-initialized.

4•2•7 Power-On RESET Switch (PRESET) - SW8

The Power-On reset switch SW8 performs Power-On reset to the MSC8101, as if the power was
re-applied to the ADS. When the Processor is reset that way, all configuration and all data residing
in volatile memories are lost. After PORST~ signal is negated, the Processor re-acquires the
power-on reset configuration data from the Flash (Altera) or Host I/F.

4•2•8 Configuration Switch - SW9

SW9 is a 8-switch DIP-Switch. This switch is connected over Altera device to MODCK(1:6) lines
of the Processor. The combination of the switches composing SW9, sets, during Power-On reset
sequence, the MODCK(1:6) field for the MSC8101. The switch SW9/7 establishes Configuration
Word Source. If SW9/7 is set to ON position Configuration Word will be loaded from the Flash, oth­erwise from Altera device (default). The Host Configuration will be chosen with SW9/8 set ON,
when SW9/8 is OFF - PPC bus has 64-bit width.

The Switch SW9 is factory set to (1 - OFF, 2 - ON, 3 - OFF, 4 - OFF (X), 5 - ON, 6 - OFF, 7,8 ­OFF).

4•3•10 Solder Bridges

The job of removing JS1-5 and soldering current
meter connections instead is very delicate and
should be done by a skilled technician.

If this process is done by unskilled hand or re­peated more than 3 times, permanent damage
might be inflicted to the MSC8101ADS.

Warning

When connecting to a GND bridge, use only IN­SULATED GND clips. Otherwise, un-insulated
clips may cause short- circuits, touching "HOT"
points around them. Failure in doing so, might
result in permanent damage to the
MSC8101ADS.

The MSC8101 has internal sources which generate Hard / Soft Resets. Among these sources are:

1) Loss of Lock Reset (Hard)

2) S/W Watch Dog Reset (Hard)

3) Bus Monitor (Hard)

4) JTAG/ONCE Reset (Hard)

In general, the MSC8101 asserts a reset line HARD or SOFT for a period 512 clock cycles after
the reset source has been identified. A hard reset sequence is followed by a soft reset sequence
that released three bus clocks later than hard reset is negated.

5•2 Local Interrupter

There are external interrupts which are applied to the MSC8101ADS via its interrupt controller:

1) ABORT (NMI)

2) ATM UNI interrupt

5•2•1 ABORT Interrupt

The ABORT (NMI), is generated by a push-button. When this button is depressed, the IRQ0 input
to the MSC8101 is asserted. The purpose of this type of interrupt, is to support the use of resident
debugger if any is made available to the MSC8101ADS. To support external (off-board) generation
of an NMI, the IRQ0

5•2•2 ATM UNI Interrupt

To support ATM UNI (User Network I/F) event report by means of interrupt, the interrupt output of
the UNI (INTB) is connected to IRQ6

Since INTB of the UNI is an open-drain output, it is possible to connect additional (off-board) inter­rupt requesters on the same IRQ6

line, the same way

5•3 Clock Generator

The MSC8101 requires a single clock source for the main clock oscillator. Use is done with 25MHz
(16.38MHz) 3.3V clock generator mounted on the 14-pin DIP socket for simpler changing. Also
clock may be provided from external clock generator (reference) via SMB-connector. All MSC8101
PPC bus timings are referenced to the clock output of the DSP. The CLKOUT is connected to a
low inter-skew buffer to split the load between all various clock consumers on the board. One of
the channel intends for the MSC8101 DLL input to eliminate buffer and path propagation delay.

Special care is taken to isolate and terminate the clock route between the on-board devices and
the MSC8101, this to provide a "clean" clock for proper operation. The main clock scheme is
shown in figure below:

5•4 Bus Buffering

In order to achieve best performance, it is necessary to reduce the capacitive load over the PPC
bus as much as possible. Therefore, the slower devices on the bus, i.e., the Flash SIMM, ATM UNI
M/P interface, BCSR and the external tool bus are buffered, while the SDRAM devices are not
buffered from the bus.

Buffers are provided over address and strobe (when necessary) lines while transceivers are
provided for data. Use is done with 74ALVT buffers (by Philips) which are 3.3V operated and 5V
tolerant

To further reduce noise and reflections, serial damping resistors may be added are placed over

5•6 Synchronous DRAM Bank

To enhance MSC8101ADS performance, 16MBytes of SDRAM is provided on the Unbuffered
PPC Bus for storage and fast data exchange. The SDRAM is configured as 2 X 2Meg X 32. Use
is done with two MT48LC2M32B2 chips by Micron or compatibles (Samsung). The part data sheet
may be obtained on the Internet at URL: http://www.micron.com/mti/msp/htm/datasheet.html.

Since it includes only 2 memory chips, the SDRAM is unbuffered from the MSC8101, avoiding the
delay associated with address and data buffers. As the volume of this sdram is far beyond any
possible future requirement, the SDRAM is soldered directly to the board.

In order to provide Host Interface held a half of the Data Bus (32bits of 64bits wide) width the DIP
switch array is present. It allows to shift address field by one bit A28->A29, A27->A28,.A12->A13.
In this case we can use one from two SDRAM chip, therewith the second chip will be disable with
BCSR’s control bit - memory space will be decreased by half. The system bus of the MSC8101 is
very fast and run up to 100MHz, therefore any type of logic for address mux puts large timing
penalty and impossible. The mux is done by jumper’s array. See FIGURE 5-2 "SDRAM Connection

5•6•1 SDRAM Programming

After power-up, SDRAM needs to be initialized by means of programming, to establish its mode of
operation. The SDRAM is programmed by issuing a Mode Register Set command. During that
command data is passed to the Mode Register through the SDRAM’s address lines. This
command is fully supported by the SDRAM machine of the MSC8101.

Mode Register programming values are shown in TABLE 5-4. "100 MHz SDRAM Mode Register

Programming" below:

5•6•2 SDRAM Refresh

Functional Description

The SDRAM is refreshed using its auto-refresh mode. I.e., using SDRAM machine 1’s periodic
timer, an auto-refresh command is issued to the SDRAM every 14 µsec, so that all 4096
rows are refreshed within spec’d
within that window, as a safety measure, covering for possible delays in bus availability for the
refresh controller.

5•7 Flash Memory SIMM

The MSC8101 is provided with 8Mbyte of 90 nsec flash memory SIMM, the SM73228XG1JHBGO
by Smart Modular Technology which is composed of four LH28F016SCT-L95 chips by Sharp,
arranged as 2M X 32 in a single bank. Support is given also to 16MBytes and 32 MBytes Simm’s.
The Flash SIMM resides on an 80 pin SIMM socket and is buffered from the 60X bus to reduce
capacitive load over it.

To minimize use of MSC8101s’ chip-select lines, only one chip-select line CS0

the Flash as a whole, while distributing chip-select lines among the module’s internal banks is done
by on-board programmable logic (BCSR), according to the Presence-Detect lines of the Flash
SIMM inserted to the MSC8101ADS.

The access time of the Flash memory provided with the MSC8101ADS is 95 nsec, however,
devices with different delay are supported as well. By reading the delay section of the Flash SIMM
Presence-Detect lines see TABLE 5-13. "Flash Presence Detect (7:5) Encoding" on page 59, the
debugger can establish via register OR0 the correct number of wait-states needed to access the
Flash SIMM (considering default system clock frequency).

The control over the Flash is done with the GPCM and a dedicated CS0
whole bank. During hard - reset initialization
reads the Flash Presence-Detect lines via BCSR and determines how to program registers BR0 &
OR0, within which the size and the delay of the region are determined. The performance of the
flash memory is shown in TABLE 5-5.:

5•8•1 ATM Port

To support the MSC8101 ATM controller, a 155.52Mbps User Network Interface (UNI) is provided
on board, connected to FCC1 of the MSC8101 via UTOPIA I/F.Use is done with PM5350 S/UNI­155-ULTRA by PMC-SIERA. Although these transceivers are capable of supporting 51.84Mbps
rate, support is given only to the higher rate.

The control over the transceiver is done using the microprocessor i/f of the transceiver, controlled
by the MSC8101 memory controller’s GPCM. Since the UNI is 5V powered and the MSC8101 3.3V
powered (5V intolerant), the UNI is buffered (LCX buffers) from the MSC8101 on both the receive
part of UTOPIA I/F and MP control ports.

The ATM transceiver may enabled / disabled at any time by writing ’0’ / ’1’ to the ATMEN~ bit in
BCSR1/2. When ATMEN~ is negated, (’1’) the MPcontrol port is also detached from the MSC8101
and its associated FCC1 may be used off-board via the expansion connectors.

The ATM transceiver reset input is driven by HRESET~ signal of the MSC8101, so that the UNI is
reset whenever a hard-reset sequence occurs. The UNI may also be reset by either asserting
ATM_RST bit in BCSR1/3 or by asserting (’1’) the RESET bit in the Master Reset and Identify /
Load Meters register via the UNI MP I/F.

The UNI transmit and receive clocks is fed with a 19.44 MHz +/- 20 ppm, clock generator, 5 V
powered, while the receive and transmit FIFOs’ clock is provided by the MSC8101, optionally from
the same clock or separate clocks, hard-configured.

The ATM SAR is connected to the physical medium by an optical I/F. Use is done with HP’s HFBR
5205 optical I/F, which operates at 1300 nm with upto 2 Km transmission range.

5•8•2 100/10 Base - T Port

A Fast Ethernet port with T.P. (100-Base-TX) I/F is provided on the MSC8101ADS. This port is
also support 10 Mbps ethernet (10-Base-T) via the same transceiver - the LXT970 by Level One.

The LXT970 is connected to FCC2 of the MSC8101 via MII interface, which is used for both ­device’s control and data path. The initial configuration of the LXT970 is done be setting desired
values at 8 configuration signals: FDE, CFG(0:1) and MF(0:4). The MF(0:4) pins however, are con­trolled by 4 - voltage levels, this to allow each pin to configure two functions. On the MSC8101ADS
these pins is driven by factory set 0Ω resistors, connected to a voltage divider, allowing future
option change during production.

Possible

Collision

D

The LXT970 reset input is driven by HRESET~ signal of the MSC8101, resetting the transceiver
whenever hard-reset sequence is taken. The LXT970 may also be reset by either asserting the
FETH_RST bit in BCSR1/5 or by asserting bit 0.15 (MSB of LXT970 control register) via MII I/F.

To allow external use of FCC2, its pins is appear at the CPM expansion connectors and the

The LXT970 is able to interrupt the MSC8101, this via IRQ7~ line. This line is shared also with the
CPM expansion connectors. Therefore, any tool that is connect to IRQ7 or IRQ6~ for that matter,
should drive these lines only with an Open Drain buffer.

To assist user’s applications and to provide convenient communication channels with both a
terminal and a host computer, two identical RS232 ports is provided on the MSC8101ADS, con­nected to SCC1 and SMC1 ports of the MSC8101. Use is done with MC145583 transceiver which
generates RS232 levels internally using a single 3.3V supply and has shutdown mode, during
which receive buffers are tri-stated. When the RS232EN1
asserted (low), the corresponding transceiver is enabled. When negated, the corresponding trans­ceiver is enter standby mode, within which the receiver outputs are tri-stated, enabling use of the
corresponding port’s pins, off-board via the expansion connectors.

5•11 Board Control & Status Register - BCSR

Most of the hardware options on the ADS are controlled or monitored by the BCSR, which is a 32
bit wide read / write register file. BCSR resides over the PPC Bus, accessed via the MSC8101’s
memory controller (see TABLE 5-3. "MSC8101ADS Chip Select Assignments" on page 44) and in
fact includes 8 registers: BCSR0 to BCSR7. Since the minimum block size for a CS region is
32KBytes and only A(27:29) lines are decoded by the BCSR for register selection, BCSR0 ­BCSR7 are duplicated many times inside that region. See also TABLE 1-1. "MSC8101ADS Spec-

ifications" on page 12.

The following functions are controlled / monitored by the BCSR:

1) PPC Data Bus width 64/32 bits.

2) CODEC Enable/Disable.

To support off-board application development, two of the power buses are connected to the ex­pansion connectors, so that external logic may be powered directly from the board. The maximum
current allowed to be drawn from the board on each bus is shown in TABLE 7-1. "Off-Board Appli-

To protect on-board devices against supply spikes, decoupling capacitors (typically 0.1µF) are
provided between the devices’ power leads and GND, located as close as possible to the power
leads, while 47 µF bulk capacitors are spread around.

7•1•1 5V Bus

Some of the ADS peripherals reside on the 5V bus. Since the MSC8101 is not 5V tolerant, buffer­ing is provided between 5V peripherals and the MSC8101, protecting the MSC8101 from the
higher voltage level. The 5V bus is connected to an external power connector via a fuse (4A).

nc...

cale Semiconductor,

Frees

To protect against reverse-voltage or over-voltage being applied to the 5V inputs a set of high­current diodes and zener diode is connected between the 5V bus GND. When either over or
reverse voltage is applied to the ADS, the protection logic blows the fuse, while limiting the mo­mentary effects on board.

7•1•2 3.3V Bus

The MSC8101, the SDRAMs, the address and data buffers are powered by the 3.3 bus, which is
produced from the 5V bus using a low-voltage drop, linear voltage regulator LM1085S, the which
is capable of driving upto 4A, facilitating operation of external logic as well.

7•1•3 1.5V Bus

The MSC8101’s internal logic and the PLL are powered with a lower-voltage power source, voltage
of which may be in a range of 0.9V - 2.2V. Obviously, there is the power-speed trade-off, i.e., lower
operation speeds may be obtained with lower voltage supply.

To provide means of evaluating this trade-off, a variable, linear power regulator - MIC29372 with
OpAmp MC33202 in feedback, is provided, so that the voltage level of that bus, may be easily
tuned, to evaluate influence.
