Can anybody help me find out how to calculate the memory adresses of the program memory etc. (program, data, ID and latches) in PIC chips? I need these to get my programmer working (it needs to know where it can program, and where it shouldn't)... I can't find all data in the datasheets... not in a way I understand it all... I did find out where the program memory of the 16F877a sits (0x0000 till 0x3FFF) but the other sectors are nowhere to be found... can anyone help? I need it for the 16F877a in the first place...
There's a big table with all the SFR's (Special Function Register Map) and space for GPR's - that's where all your port latches etc are and where you can store variables. For the ID search the index for "ID Locations"!
yeah, but the numbers there are 2-numbered hexadecimal numbers? :S somehow, the program memory is (on the 16F877a) from 0x0000 till 0x3FFF... oh wait Found a nice datasheet on microchip's site, one specificly designed for explanation of 'serial programming' for who's interested: a linky
