15 SPECIAL PERIPHERALS, CONFIGURATION
15.1 The special function interface for MICROSPACE
computers SFI
All functions are performed by starting the SW-interrupt 15hex with the following arguments:
Function: WRITE TO EEPROM
Number:
E0h
Description:
Writes the Data byte into the addressed User-Memory-Cell from
the serial EEPROM. The old value is automatically deleted
Input values:
AH 78h DLAG Int15 function
AL E0h Function request
BX Address in EEPROM (0-1024 Possible)
CL Data Byte to store
SI 1234h User-Password (otherwise EEP is write protected)
Output values:
None, all registers are preserved
Function: READ FROM EEPROM
Number:
E1h
Description:
Reads the Data byte from the addressed User-Memory-Cell of
the serial EEPROM
Input values:
AH 78h DLAG Int15 function
AL E1h Function request
BX Address in the EEPROM (0-1234 Possible)
SI 1234h User-Password (DLAG-Password for access to the
DLAG-Memory-Cells)
Output values:
AL Data Byte
Function: WRITE SERIAL NUMBER
Number:
E2h
Description:
Writes the Serialnumber from the serial EEPROM into the ad-
dressed DLAG-Memory-Cell. The old value is automatically de-
leted
Input values:
AH 78h DLAG Int15 function
AL E2h Function request
BX,
CX,
DX
Serial Number
SI Password
