#161795 - EECON is SFR Responding to: ???'s previous message |
I did not go further in your code than the first few lines: the EECON is NOT mapped to the external memory, hence NOT accessed via MOVX. EECON is a SFR, hence accessed directly, such as in:
EECON EQU 96h [...] mov EECON,#some_value You should read the relevant parts of the "primer" document: http://www.atmel.com/dyn/resou...oc3655.pdf JW |
