TC – Timer/Counter
29.1 Overview
The TC consists of a counter, a prescaler, compare/capture channels and control logic. The counter can be set to count
events, or it can be configured to count clock pulses. The counter, together with the compare/capture channels, can be
configured to timestamp input events, allowing capture of frequency and pulse width. It can also perform waveform
generation, such as frequency generation and pulse-width modulation
events, or it can be configured to count clock pulses. The counter, together with the compare/capture channels, can be
configured to timestamp input events, allowing capture of frequency and pulse width. It can also perform waveform
generation, such as frequency generation and pulse-width modulation
(PWM)
