Expanded Register File (ERF). The register file has been expanded to allow for addi-
tional system control registers, mapping of additional peripheral devices and input/output
ports into the register address area. The Z8 register address space RO through R15 is
implemented as 16 groups of 16 registers per group (see
are known as the Expanded Register File (ERF).
The low nibble (D3-D0) of the Register Pointer (RP) select the active ERF Bank, and the
high nibble (D7-D4) of register RP select the working register group. Three system con-
figuration registers reside in the Expanded Register File at bank FH: PCON, SMR, and
WDTMR. The rest of the Expanded Register is not physically implemented and is
reserved for future expansion.
