IR/Low-Voltage Microcontroller
GENERAL DESCRIPTION (Continued)
To unburden the program from coping with such real-time
problems as generating complex waveforms or receiving
and demodulating complex waveform/pulses, the Z86L7X
family offers a new intelligent counter/timer architecture
Zilog
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 (Figure
2).
