Enhanced Type TM Operating Modes

The Enhanced Type TM can operate in one of five operating modes, Compare Match Output Mode,
PWM Output Mode, Single Pulse Output Mode, Capture Input Mode or Timer/Counter Mode. The
operating mode is selected using the TnAM1 and TnAM0 bits in the TMnC1, and the TnBM1 and
TnBM0 bits in the TMnC2 register.
