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 battery errors
DX Number of 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 en-
abled, the user application must perform a strobe at least every
800ms, otherwise 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 CPU-thermal sensor
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
