6.3 Adapter Card Mounting
PC/104 and PC/104-Plus adapter cards are mounted in a "stack-through" manner. Adapter
cards are designed with plugs on their undersides that mate with the PC/104 socket
connectors of MOPS/520. PC/104 adapters can support the socket connector version on their
topside and allow further "stacking" of adapters.
6.4 I/O Address Mapping Limitation
Only I/O addresses below 400h are mapped to the external ISA respectively PC104 bus. All
higher I/O addresses are directed to PCI.

MOPS/520 Product Manual
Serial Communication Interface
8.3 Limitations
The SC520 integrated serial ports (serial port C and D on the MOPS/520) show two
deviations from the standard UART behaviour:
The delta ring indicator bit in the modem status register (bit 2) is only set when the ring
indicator signal has changed from an active to an inactive state since the last time the modem
status register was read.
Usually this bit is set for RI changes from inactive to active as well.
In 16550 compatible mode a received data interrupt is generated when the very first data byte
of a continuous data stream is placed in FIFO. This error only occurs for the first character of
a continuous data stream received by the UART. Following the FIFO time-out interrupt for
the first character received, the remainder of the data stream will be indicated according to
the trigger value set in the RFRT bits of the UART FIFO control registers.

9.2 Configuration
The MOPS/520 parallel ports are fully bi-directional. The bi-directional functions are
compatible with those of a PS/2 style parallel port. This functionality is always available and
does not conflict with normal printer use. The parallel port mode, I/O addresses, and IRQs
are defined in the BIOS Setup utility.
9.3 Limitations
Due to chipset limitations, parallel port mode ECP as well as parallel port base address 3BCh
(in any mode) cannot be used when a PCI video adapter is installed on the system. With ISA
video adapters these restrictions do not apply

14.2 Power Pins
The MOPS/520 is a +5 V only module. Nevertheless the power connector offers the
possibility to supply with the additional voltages +12V, -12V and -5V, which may be
necessary for other boards in the PC/104 system. The power consumption of all available
power pins on the MOPS/520 is limited to 5A in total (1A per pin, with 2 pins on the power
connector, 2 pins on the XT-bus and 1 pin on the AT-bus) and at GND up to 8A. Systems
consuming more then 2A shouldn’t be served over the power connector only. Systems
consuming more then 5A must provide power supply through an additional connector on
another board.
The MOPS/520 is not a replacement for a backplane. It is strictly recommended to use all
Power Pins on the PC/104 connector for power supply of the MOPS/520 and additional I/O
cards. It is not acceptable to use only the power pins of the PC/104plus PCI connector for
power supply of the full PC/104 stack.
14.3 VBAT (system battery connection)
This pin connects a system battery to all modules.
The battery voltage has to be higher than 2.0V and lower than 3.3V. A 3V battery is
recommended.
Please note that there is no battery needed to hold the CMOS-setup data. Your configuration
concerning hard disks, floppy drives etc. is automatically saved in an onboard FRAM.
Nevertheless the battery is necessary to serve the CMOS date and time while power
consumption is turned off.

Watchdog Timer
15. WATCHDOG TIMER
The watchdog timer feature of the MOPS/520 provides a means to insure the integrity of
system operation. The timer is integrated into the Élan™SC520 Microcontroller. When
enabled, system software must refresh the timer within the specified timeout period or the
timer will be triggered. The timer can be programmed to either reset the system or initiate a
Non-Maskable Interrupt (NMI) when triggered.
15.1 Watchdog BIOS Interface
The watchdog timer may be enabled or disabled in BIOS Setup or through an Interrupt 15h
BIOS function call. The Interrupt 15h Watchdog functions have the following calling
conventions:

The function Init watchdog must be called only once. The two parameters timeout time and
trigger event must be set. The watchdog must be reset during the timeout time with the
trigger watchdog function. Otherwise a RESET or NMI will occur depending on trigger
event
The trigger and the delay time can be set in steps of 0.2 sec.
The theoretical maximum values are:
Ÿ Timeout time
65535*0.2sec. = 13107s ≅ 3h 38min

16. CAN-BUS
The CAN-Bus on the MOPS/520 Boards is based on INTEL 82527 controller.
The 82527 serial communications controller is a highly integrated device that performs serial
communication according to the CAN protocol. It performs all serial communication
functions such as transmission and reception of messages, message filtering, transmit search
and interrupt search with minimal interaction from the host microcontroller, or CPU.
The 82527 is Intel's first device to support the standard and extended message frames in CAN
Specification 2.0 Part B. It has the capability to transmit, receive, and perform message
filtering on extended message frames. Due to the backward compatible nature of CAN
Specification 2.0, the 82527 also fully supports the standard message frames in CAN
Specification 2.0 Part A.
A PC82C251 from PHILIPS acts as an interface to the physical bus. This is a CAN
transceiver for 24 V systems.

17. THE JIDA STANDARD
JIDA is the abbreviation for JUMPtec Intelligent Device Architecture.
Every board with onboard BIOS extension shall support the following function calls, which
supply information about the board. JIDA functions are called via Interrupt 15h with
AH=EAh, AL=function number, DX=4648h (security word), CL=board number (starting
with 1).
The interrupt will return with CL#0 if a board with the number specified in CL does not exist.
CL will be equal to 0 if the board number exists. In this case, the content of DX is used to
determine if the operation was successful. DX=6B6Fh indicates successful operation; any
other value indicates an error.
To get information about the installed boards following the JIDA standard, the following
procedure is recommended:
Call “Get Device ID” with CL=1. The name of the first device installed will be returned.
If result was “Board exists” (CL=0), increment CL and call “Get Device ID” again.
Repeat until result is “Board not present” (CL#0).
You now know the names of all boards within your system that follow the JIDA standard.
More information about a specific board may then be obtained by calling the appropriate
inquiry function with the board’s number in CL.
NOTE: Association between board and board number may change due to configuration
changes. Do not rely on any association between board and board number. Always use
the procedure described in the preceding paragraph first, to determine the association
between board and board number.
The manual and sample code for the JIDA is available from our web page at

19.3 BIOS Update with Phoenix Phlash
Phoenix Phlash gives you the ability to update your BIOS from a floppy disk without having
to install a new ROM chip. Phoenix Phlash is a utility for ‘flashing’ a BIOS to the Flash
ROM installed on the MOPS/520.
Use Phoenix Phlash for the following tasks only:
• Update the current BIOS with a newer version
• Restore a BIOS when it has become corrupted (see below)
Phoenix Plash can be downloaded as a compressed file CRISP489.ZIP from the JUMPtec
web page and contains the following files:
MAKEBOOT.EXE
CRISBOOT.BIN
MINIDOS.SYS
PHLASH.EXE
WINCRISIS.EXE
WINCRISIS.HLP
PLATFORM.BIN
BIOS.ROM
Creates the custom boot sector on the Crisis Recovery Diskette

Programs the flash ROM
Executable file for creating the Crisis Recovery Diskette from Windows

Actual BIOS image to be programmed into flash ROM
To install Phoenix Phlash on your hard disk, unzip the content of CRISP489.ZIP into a local directory,
presumable C:\PHLASH.
To create the Crisis Recovery Diskette insert a clean diskette into drive A: or B: and execute
WINCRISIS.EXE. This copies four files onto the Crisis Recovery Diskette:

Revision 1.5
MOPS/520 Product Manual
Appendix B: BIOS
If the BIOS image (BIOS.ROM) changes due to an update or bug fix, you can easily update
the Crisis Recovery Disk. Simply copy the new BIOS.ROM image onto the diskette.
You can run Phoenix Phlash in one of two modes:
•
•
Command Line Mode
Crisis Recovery Mode
Use the Command Line mode to update or replace your current BIOS. To execute Phlash in
this mode, move to the Crisis Recovery Disk and type PHLASH. Phoenix Phlash will
automatically update the BIOS. Phlash may fail if your system is using memory managers, in
which case the utility will display the following message:
Cannot flash when memory manager is present.
If you see this message after you execute Phlash, you must disable the memory manager on
your system.
19.4 Boot Block Support
Updating the BIOS may create a possible hazard: power failures or fluctuations that occur
during the Flash ROM update can damage the BIOS code, making the system unbootable.
To prevent this possible hazard, the MOPS/520 is equipped with a boot block Flash ROM.
The boot block region contains a fail-safe recovery routine. If the boot block code finds a
corrupted BIOS (checksum fails), it will boot into the crisis recovery mode and load a BIOS
image from a special crisis diskette (see above).
Additionally, the end user can insert an update key into the parallel port to force initiating the
boot block recovery routine.
For further information on the update key and the crisis diskette, please visit the JUMPtec
web page.

Appendix E: Limitations
22. APPENDIX E: LIMITATIONS
22.1 Parallel Port
Due to certain chipset limitations, parallel port mode ECP, as well as parallel port base
address 3BCh (in any mode), cannot be used when a PCI video adapter is installed on the
system.
With ISA video adapters these restrictions do not apply.
22.2 Serial Ports
The SC520 integrated serial ports (serial port C and D on the MOPS/520) show two
deviations from the standard UART behavior:
The delta ring indicator bit in the modem status register (bit 2) is only set when the ring
indicator signal has changed from an ‘active’ to ‘inactive’ state since the last time the modem
status register was read. Respectively, this bit is set for RI changes from ‘inactive’ to
‘active’.
In 16550 compatible mode, a received data interrupt is generated when the very first data
byte of a continuous data stream is placed in FIFO. This error only occurs for the first
character of a continuous data stream received by the UART. Following the FIFO time-out
interrupt for the first character received, the remainder of the data stream will be indicated
according to the trigger value set in the RFRT bits of the UART FIFO control registers.
22.3 I/O Address Mapping
Only I/O addresses below 400h are mapped to the external ISA bus. All higher I/O addresses
are directed to PCI.
JUMPtec®
46
Revision 1.5
MOPS/520 Product Manual
Appendix E: Limitations
22.4 System Clock Deviation
In PC/AT compatible systems, system boot code usually programs the Programmable Interval
Timer Channel 0 Count (PIT0CNT) register (port 0040h) to a value of FFFFh. If the timer is
based on the PC/AT standard clock of 1.19318 MHz, this results in a periodic IRQ0
generation every 54.93 ms, which is used to keep accurate time of day.
However, as the internal timer clock source of the SC520 is only 1.1892 MHz, setting the
standard counter value results in a slower IRQ0 generation rate and inaccurate time of day.
The MOPS/520 BIOS takes care of the deviating clock rate of the SC520 by setting the
PIT0CNT to a value of FF25h. However, this only guarantees an accurate system clock for
operating systems like DOS, which do not change the value set by the BIOS. If an operating
system (like e.g. Windows 98) re-initializes the PIT0CNT with the standard PC value of
FFFFh, it will result in significant system clock deviation.
To solve this problem, set the PIT0CNT to the MOPS/520 value of FF25h again after the
operating system has been started.
22.5 Windows 2000 Support
Windows 2000 (at least an unmodified standard version) does not run on systems with ISA
IDE controllers. During installation or start of a pre-installed system, Windows fails
displaying the error message INACCESSIBLE_BOOT_DEVICE. As the MOPS/520 uses an
ISA IDE interface, at least a standard Windows 2000 version cannot be installed or run on
the MOPS/520.
22.6 ISA SCSI Support
Due to limitations concerning 16Bit DMA transfers in conjunction with the asynchronous
ISA bus timing most ISA SCSI cards can not be used with the MOPS/520.
22.7 Video Support
ISA Graphic Adapters depending on additional ports above 0400h for some special
initialization cannot be used with the MOPS/520.
JUMPtec®
47
Revision 1.5
MOPS/520 Product Manual
Appendix E: Limitations
22.8 Watchdog NMI Handling
Although set to NMI mode, the SC520 watchdog will only generate a NMI for the first
watchdog timeout. The next time the watchdog timer expires a reset will be generated.
To avoid this, the watchdog NMI interrupt service routine must clear bit 12 of the SC520
Watchdog Timer Control register by writing a 1 to this bit. The key sequence 3333h followed
by CCCCh must be sent to the register (which is memory mapped to address E400:0CB0)
before it can be write accessed. The following code sequence is meant to illustrate the
described procedure:
.
.
unsigned int wdstore;
volatile unsigned int far *WDTMCTRL;
WDTMCTRL = ((void far *) 0xE4000CB0;
.
.
void interrupt NmiIsr (void)
{
wdstore = *WDTMCTRL;
*WDTMCTRL = 0x3333;
*WDTMCTRL = 0xCCCC;
wdstore = wdstore | 0x1000;
*WDTMCTRL = wdstore
