How can I reserve a specific memory location?

[chingB]

Hi,

Anybody has an idea of how can I reserver a specific location of the on-chip program memory?

Does CCS has a built-in function for reading/writing the on-chip program memory?

Any comments and suggestions?

Thank you.

To reserve location you can use #org. Quoting from the manual: Follow the ORG with a {} to only reserve the area with nothing inserted by the compiler. You may want to take a look at #ROM too.

To read/write the on-chip program memory you can use the read_program_eeprom()/write_program_eeprom () functions.

Judging by the code generated in the .LST file, on a PIC16F87x read_program_eeprom() takes around 20 instruction cycles and write_program_eeprom() takes around 40 instruction cycles to finish.
