18F1320 ... Strange Memory

[Acetronics2]

Hi all,

I wrote a nice piece of code ( 3200 hex lines ...) for a 16F648 an a 16F88 : Everything works OK ! ... thank you.

BUUUUUT, Trying to use it aboard a 18F1320 ... things become quite funny :

Let's see:

Program runs ... but...

I have to memorize in the EEPROM 8 values "in a row" ( from 1 to 8 ) and then Three others, one by one, at locations 10,11, and 12.

The first 8 are well Stored ... but the 3 others never want to be stored !!!

Somewhere else, after that, I can modify values 1 and 2 ...

They are properly modified and stored !!!!

So, shortly ... my 18F1320 seems to have only 8 addressable EEPROM registers.
I tried to push the 3 lonesome values to $11, 12 and 13 ... no more result.

Anyone understanding that ???

( Setting WREN to 1 doesn't modify anything ... )
