The Timer/Counter type D (TCD) is a high-performance waveform generator that consists of an asynchronous counter, a prescaler, and compare, capture and control logic.

The TCD contains a counter that can run on a clock that is asynchronous to the peripheral clock. It contains compare logic that generates two independent outputs with optional dead-time. It is connected to the Event System for capture and deterministic Fault control. The timer/counter can generate interrupts and events on compare match and overflow.

This device provides one instance of the TCD peripheral, TCD0.
