Motor Control Timer (MCTM)

Introduction

The Motor Control Timer consists of one 16-bit up/down-counter, four 16-bit Capture / Compare
Registers (CCRs), one 16-bit Counter-Reload Register (CRR), one 8-bit Repetition Counter (REPR)
and several control / status registers. It can be used for a variety of purposes which include general
time measurement, input signal pulse width measurement, output waveform generation for signals
such as single pulse generation or PWM generation, including dead time insertion. The MCTM
supports an encoder interface using a quadrature decoder with two inputs.
