FUNCTIONAL DESCRIPTION (Continued)

nal program and data memory from addresses

16384

/32768 to 65535.

Expanded Register File (ERF).

The Z8 register file is ex-

panded to allow for additional system control registers, and

for mapping of additional peripheral devices along with I/O

ports into the register address area. The Z8 register address

space R0 through R15 is implemented as 16 groups of 16

registers per group (Figure 19). These register groups are

known as the Expanded Register File (ERF). Bits 7–4 of reg-

ister RP select the working register group. Bits 3–0 of reg-

ister RP select the expanded register group. Three system

configuration registers reside in the Expanded Register File

at Bank F (PCON, SMR, WDTMR). The rest of the Expand-

ed Register is not physically implemented, and is open for

future expansion.
