(TPnMD2 to TPnMD0 = 010)
In the external trigger pulse output mode, 16-bit timer/event counter P waits for
a trigger when the TPnCTL0.TPnCE bit is set to 1. When the valid edge of an
external trigger input signal is detected, 16-bit timer/event counter P starts
counting, and outputs a PWM waveform from the TOPn1 pin.
Pulses can also be output by generating a software trigger instead of using the
external trigger. When using a software trigger, a square wave that has one
cycle of the PWM waveform as half its cycle can also be output from the
TOPn0 pin.
