Register File
Note:
The register file (bank 0) consists of 4 I/O port registers, 236 general-purpose reg-
isters, and 16 control and status registers (R0–R3, R4–R239, and R240–R255,
respectively), plus two expanded registers groups (Banks D and F). Instructions
can access registers directly or indirectly through an 8-bit address field. This
allows a short, 4-bit register address using the register pointer
4-bit mode, the register file is divided into 16 working register groups, each occu-
pying 16 continuous locations. The register pointer addresses the starting location
of the active working register group.
Default setting after reset = 0000 0000
R253 RP
D7 D6 D5
Working register group E0–EF of Bank 0 are only accessed
through working registers and indirect addressing modes.
