12 Standard Timer Module
The standard timer module consists of a 16-bit software-programmable counter driven by a prescaler.
It contains eight complete 16-bit input capture/output compare channels and one 16-bit pulse accumu-
lator.
This timer can be used for many purposes, including input waveform measurements while simulta-
neously generating an output waveform. Pulse widths can vary from less than a microsecond to many
seconds. It can also generate PWM signals without CPU intervention.
