After a reset, register pointers RP0 and RP1 automatically select two 8-byte register slices in set 1, locations C0H–
CFH, as the active 16-byte working register block:
RP0 → C0H–C7H
RP1 → C8H–CFH
This 16-byte address range is called common area. That is, locations in this area can be used as working registers
by operations that address any location on any page in the register file. Typically, these working registers serve as
temporary buffers for data operations between different pages.
