CL Data Byte to store
SI 1234h User-Password (otherwise EEP is write protected)
None, all registers are preserved
READ FROM EEPROM
E1h
Reads the Data byte from the addressed User-Memory-Cell of
the serial EEPROM
AH 78h DLAG Int15 function
AL E1h Function request
BX Address in the EEPROM (0-1234 Possible)
