FUNCTIONAL DESCRIPTION
(Continued)
Program Memory.
The Z86319 can address up to 2 KB
of internal program memory (Figure 14). The first 12 bytes
of program memory are reserved for the interrupt vectors.
These locations contain four 16-bit vectors that corre-
spond to the four available interrupts. Bytes 0-2047 are
on-chip mask-programmed ROM.
Register File.
The Register File consists of three I/O
port registers, 125 general-purpose registers, and 14 con-
trol and status registers, R0-R3, R4-R127 and R241-
R255, respectively (Figure 15). The Z86319 instructions
can access registers directly or indirectly via an 8-bit ad-
dress field. This field allows short, 4-bit register addressing
using the Register Pointer. In the 4-bit mode, the register
file is divided into eight working register groups, each oc-
cupying 16 continuous locations. The Register Pointer ad-
dresses the starting location of the active working-register
group.
