FUNCTIONAL DESCRIPTION
(Continued)
Program Memory.
The Z8 addresses up to 512 bytes of
internal program memory (Figure 12). The first 12 bytes of
program memory are reserved for the interrupt vectors.
These locations contain six 16-bit vectors that correspond
to the six available interrupts. Bytes 0-511 are on-chip one-
time programmable ROM.
Register File.
The Register File consists of three I/O port
registers, 61 general-purpose registers, and 12 control
and status registers R0-R3, R4-R127 and R241-R255, re-
spectively (Figure 13). General-purpose registers occupy
the 04H to 7FH address space. I/O ports are mapped as
per the existing CMOS Z8. The instructions can access
registers directly or indirectly through an 8-bit address
field. This allows short 4-bit register addressing using the
Register Pointer. In the 4-bit mode, the register file is divid-
ed into eight working register groups, each occupying 16
continuous locations. The Register Pointer (Figure 14) ad-
dresses the starting location of the active working-register
group.
