PIC18F67J90 memory map

Where everything sits, at its exact address. The PIC18F67J90 keeps program and data apart (Harvard): program memory holds 16-bit instruction words, addressed in bytes, while the special function registers and the general-purpose RAM share the banked data memory.

Program memory
