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 which 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.
