Registers and memory locations:
• EEDATA = SFR 0x9E
• EECTRL = SFR 0x9F
• *source = pointer to EEPROM address for read or write
• *destination = pointer to XRAM address
• count = byte count for multiple read/write
If the EEPROM interrupt service routine (INT5) returns the value 0x80 (illegal command), the loop should be exited, all
registers should be refreshed and the operation should be restarted.
EEDATA= 0xA1 (read command)
EECTRL = 0x03 (transmit data command)

count==1?
*source++ = EEDATA
EECTRL = 0x05 (stop command)
Clear all registers
End
NO
*source++ = EEDATA
EECTRL = 0x02 (multiple read with ACK command)
