There are up to five TC peripheral instances. Up to four TCs (TC[3:0]) are in PD1, whereas TC4, present in all device configurations, is always located in power domain PD0.
Each TC consists of a counter, a prescaler, compare/capture channels and control logic. The counter can be set to count events, or clock pulses. The counter, together with the compare/capture channels, can be configured to timestamp input events or IO pin edges, allowing for capturing of frequency and/or pulse width.
A TC can also perform waveform generation, such as frequency generation and pulse-width modulation.
