Register File
The register file (bank 0) consists of 4 I/O port registers, 237 general-purpose reg-
isters, 16 control and status registers (R0–R3, R4–R239, and R240–R255,
respectively), and two expanded registers groups in Banks D (see Table 15) and
F. Instructions can access registers directly or indirectly through an 8-bit address
field, thereby allowing a short, 4-bit register address to use the Register Pointer
(Figure 17). In the 4-bit mode, the register file 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.
