PIC16CR74 memory map
Where everything sits, at its exact address. The PIC16CR74 keeps program and data apart (Harvard): program memory holds 14-bit instruction words, addressed in words, while the special function registers and the general-purpose RAM share the banked data memory.
Data memory
Banked: special function registers and general-purpose RAM in each bank.
