3.14.6 12-bit Timer/Counter D with PWM

3.14.6.1 Introduction

The Timer/Counter type D (TCD) is a flexible 12-bit timer that can perform complex actions as well as the basic functions of a simple timer. The TCD is a high-performance waveform generator consisting of a counter that can run on a clock which is asynchronous to the peripheral clock, a prescaler, as well as compare, capture and control logic. The compare logic generates two independent outputs with optional dead time. The TCD is also connected to the Event System for capture and deterministic fault control. The timer/counter can generate interrupts and events on compare match and overflow.
