PIC18F56Q84 memory map
Where everything sits, at its exact address. The PIC18F56Q84 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.
Data memory
Banked: special function registers and general-purpose RAM in each bank.
