Memory Block Copy for PIC16F877
Thomas N email (remove spam text)
For the 16F877 IC, the RAM space of bank0 from 0x70 to 0x7F can be accessed
from any bank. I love this feature!
Is there any way to expand it? If yes, would you please tell me how I can do
If no, is there any way to copy the whole memory block or I have to do the
movf x, w ; assume I am in bank 0
bank1 ; switch to bank 1
movwf y ; store it
bank2 ; switch to bank 2
movwf z ; store it
bank4 ; switch to bank 3
movwf zzz ; store it
If I want to expand the mirror memory to another 16 locations, it seems like
I have to write lots of code! Any there any faster and more efficent way?
Thank a lot for all you help!
