39.5 Product Dependencies
39.5.1 I/O Lines
The pins used for interfacing the PWM are multiplexed with PIO lines. The programmer must first program the PIO
controller to assign the desired PWM pins to their peripheral function. If I/O lines of the PWM are not used by the
application, they can be used for other purposes by the PIO controller.
All of the PWM outputs may or may not be enabled. If an application requires only four channels, then only four PIO lines
will be assigned to PWM outputs.
