Study the chapter called "Data EEPROM Memory" in your datasheet. Tells you all about it, and the sequence of commands necessary to read and write the EEPROM. It describes the registers involved and even has some simple asm code to demo how to do it.im using MC18, read through the compiler library but i dun see any specific functions for reading/writing into the data EEPROM.
hoping to get some guide to the easiest way for writing into the ROM? ..cant seem to find ath bout this online..thx
