possible to know where the count is with respect to the duty value and
software can be used to make adjustments by turning the enable bit off
and on.
The four PWM channel outputs share general-purpose port P pins.
Enabling PWM pins takes precedence over the general-purpose port.
When PWM channels are not in use, the port pins may be used for
discrete input/output.
