6.8 SERIAL EEPROM PROGRAMMING
The X5043 serial EEPROM has 512 (200h) bytes on non-volatile memory. Section
6.7 describes using the serial EEPROM for saving CMOS RAM settings. Addresses
00h - 7Fh in the serial EEPROM are reserved for holding CMOS RAM data,
addresses 80h and 81h contain a checksum for the CMOS data, and addresses 82h
- 0FFH are reserved for future DSP Design use. Addresses 100h - 1FFh remain
available for users.
The TP3EE.EXE program allows individual bytes in the EEPROM to be written and
read. It also provides a way of testing the EEPROM, enabling and testing the
watchdog timer, and copying the CMOS SRAM into the EEPROM. It has the following
parameters:
-rxxx -r reads the data from the serial EEPROM at the address <xxx>, and displays
it on the screen. The xxx parameter is a hexadecimal number in the range 0 -
1FFh.
-wxxx -w writes data into the serial EEPROM at the address defined by the <xxx>
parameter. The data written is the hexadecimal byte specified by the -d
parameter. The xxx parameter is a hexadecimal number in the range 0 -
1FFh.
-dxx -d defines the data value to be written to the serial EEPROM by the -w
parameter. The xx parameter is a hexadecimal number in the range 0 - FFh.
-t
-t tests the serial EEPROM, by writing to every location. The previous data is
destroyed.
-c -c copies the contents of the CMOS SRAM into the serial EEPROM.
-s -s saves the contents of the serial EEPROM into a file on the current drive
called TP3CMOS.DAT. All 512 bytes are saved. Together with the –p
command this can be used to save and restore known CMOS memory
configurations prior to putting TP400 systems into production.
-p
-p programs the serial EEPROM with the contents of a file on the current drive
called TP3CMOS.DAT. All 512 bytes are written. Together with the –s
command this can be used to save and restore known CMOS memory
configurations prior to putting TP400 systems into production.
-e
-e enables the watchdog timer. The TP400 will be reset unless the watchdog
is kicked (see the -k parameter). This is only used for testing purposes.
