Function: READ INFO 3 FROM EEPROM
(READCOUNTER –LOW 2 BYTE OF 3 BYTE COUNTER)
Number: EAh
Description: Reads the information bytes out of the serial EEPROM
Input values: AH 78h DLAG Int15 function
AL EAh Function request
Output values: AX Number of boot errors
BX Number of setup entries
CX Number of low batteries errors
DX Number power on starts
Function: WATCHDOG
Number: EBh
Description:
Enables, strobes and disables the WATCHDOG. After power-up,
the Watchdog is always disabled. Once the Watchdog has been
enabled, the user application must perform a strobe at least
every 800ms, other- wise the watchdog performs a hardware
reset
Input values: AH 78h DLAG Int15 function
AL EBh Function request
BL 00h Disable
BL 01h Enable
BL FFh Strobe
01h..FFh Enable Watchdog / retrigger
BH 00h = BL -> number of sec. / 01h = BL -> number of min.
Output value: AL 01h Watchdog timer time-out occurred
Function: Read Temperature of THE CPU
Number:
ECh
Description:
Reads the temperature from the LM75 or the CPU-
thermalsensor
Input values: AH 78h DLAG Int15 function
AL ECh Function request
Output value: BL 00h =>value OK, otherwise error
CL ADM1023 TempBit 7= 01h neg. /*1C
DX CPU Temp (from the ADM1023) Bit 10= 01h neg. / *0125C
