8.3 Timer Operation
The core of the capture/compare timer is a 16-bit free-running counter.
The counter provides the timing reference for the input capture and
output compare functions. The input capture and output compare
functions provide a means to latch the times at which external events
occur, to measure input waveforms, and to generate output waveforms
and timing delays. Software can read the value in the 16-bit free-running
counter at any time without affecting the counter sequence.
Because of the 16-bit timer architecture, the input/output (I/O) registers
for the input capture and output compare functions are pairs of 8-bit
registers.
