8.2 Introduction
This section describes the operation of the 16-bit capture/compare timer.
Figure 8-1
summary of the timer input/output (I/O) registers.
8.3 Timer Operation
The core of the capture/compare timer is a 16-bit free-running counter.
The counter is the timing reference for the input capture and output
compare functions. The input capture and output compare functions can
latch the times at which external events occur, measure input
waveforms, and generate output waveforms and timing delays. Software
can read the value in the counter at any time without affecting the
counter sequence.
