15.4.3.9.2 PWM Generator Trigger Output

One of the PWM Generator internal events may be selected to drive the PWM Generator trigger output. The PWM Generator trigger output signal is selected using the PGTRGSEL[2:0] bits (PGxEVT1[18:16]) with the selection being either EOC or one of the three TRIGx compare events. Using one of the TRIGx events as an SOC trigger for another PWM Generator is useful for implementing a variable phase PWM. The phase relationship between two different PWM Generators can be controlled by the value written to the TRIGx registers.
