Section 8. Timer
8.1 Contents
8.2 Introduction
The timer consists of a 16-bit, software-programmable counter driven by
a fixed divide-by-four prescaler. This timer can be used for many
purposes, including input waveform measurements while
simultaneously generating an output waveform. Pulse widths can vary
from several microseconds to many seconds. Refer to Figure 8-1 for a
timer block diagram.
Each specific functional segment (capability) is represented by two
registers. These registers contain the high and low byte of that functional
segment. Generally, accessing the low byte of a specific timer function
allows full control of that function; however, an access of the high byte
inhibits that specific timer function until the low byte also is accessed.
