GENERAL DESCRIPTION
(Continued)
consumer, automotive, computer peripheral, and battery
operated hand-held applications.
There are four basic address spaces available to support
a wide range of configurations: Program Memory, Regis-
ter File, Expanded Register File, and External Memory.
The register file is composed of 256 bytes of RAM. It in-
cludes four I/O port registers, 16 control and status regis-
ters and the rest are General Purpose registers. The Ex-
panded Register File consists of two additional register
groups (F and D). External Memory is not available on 28-
pin versions.
To unburden the program from coping with such real-time
problems as generating complex waveforms or receiving
and demodulating complex waveform/pulses, the Z86LXX
family offers a new intelligent counter/timer architecture
with 8-bit and 16-bit counter/timers (Figure 1). Also includ-
ed are a large number of user-selectable modes, and two
on-board comparators to process analog signals with sep-
arate reference voltages (Figure 2).
Notes:

active Low, only).
