Register File. The register file consists of three I/O port registers, 236/125 general-pur-

pose registers, 15 control and status registers, and three system configuration registers in

the expanded register group. The 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 (see Figure 24). In the 4-bit mode, the register file is divided into 16 working reg-

ister groups, each occupying 16 continuous locations. The Register Pointer addresses the

starting location of the active working-register group.

Note: Register Group E0-EF can only be accessed through working register

and indirect addressing modes.
