Expanded Register File
Note:
The register file has been expanded to allow for additional system control regis-
ters and for mapping of additional peripheral devices into the register address
area. The Z8 register address space (R0 through R15) has been implemented as
16 banks, with 16 registers per bank. These register groups are known as the
ERF (Expanded Register File). Bits 7–4 of register RP select the working register
group. Bits 3–0 of register RP select the expanded register file bank.
An expanded register bank is also referred to as an expanded
register group (see Figure 16).
