Note:
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
ister groups, each occupying 16 continuous locations. The Register Pointer addresses the
starting location of the active working-register group.
Register Group E0-EF can only be accessed through working register
and indirect addressing modes.
