Expanded Register File
The register file has been expanded to allow for additional system control registers 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
