Register File
The register file (bank 0) consists of 4 I/O port registers, 237 general-purpose registers,
16 control and status registers (R0–R3, R4–R239, and R240–R255, respectively), and two
expanded registers groups in Banks D (see
directly or indirectly through an 8-bit address field, thereby allowing a short, 4-bit
register address to use the Register Pointer
is divided into 16 working register groups, each occupying 16 continuous locations. The
Register Pointer addresses the starting location of the active working register group.
Working register group E0–EF can only be accessed through working registers and
indirect addressing modes.
