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.
