I have had the same problem. I used the said code fragment. After
inserting some NOPs it came out the EEPROM operation fails if the highest
bit of the data to be written is 1, i. e. data GE 80h. Such way, I split
the data in two nibbles and I write the nibbles with high nibble set to
zero. Then it works. However, it is not very storage efficient method
Yesterday I took part on a Microchip seminar. The engineer said the
problem is known and caused by some timing specification issue. They will
post the corrected routine ASAP.
I hope this helps.
