Enhanced Capture (eCAP) Module
15.3.3.5 Application of the APWM Mode
15.3.3.5.1 Simple PWM Generation (Independent Channel/s) Example
In this example, the eCAP module is configured to operate as a PWM generator. Here a very simple
single channel PWM waveform is generated from output pin APWMn. The PWM polarity is active high,
which means that the compare value (CAP2 reg is now a compare register) represents the on-time (high
level) of the period. Alternatively, if the APWMPOL bit is configured for active low, then the compare value
represents the off-time.
