The Timer/Counter (TC) module provides a set of timing and counting related functionality, such as the generation of periodic waveforms, the capturing of a periodic waveform's frequency/duty cycle, and software timekeeping for periodic operations. TC modules can be configured to use an 8-, 16-, or 32-bit counter size.
This TC module for the SAM is capable of the following functions:
Generation of PWM signals
Generation of timestamps for events
General time counting
Waveform period capture
Waveform frequency capture
Figure 1 shows the overview of the TC module design.
