15.4.1.3 Minimum PWM Period and Pulse Width

The PWM module has some restrictions regarding minimum PW periods and pulse widths. Depending on the operating mode, the pulse width can also be dependent on PHASE and TRIGy, in addition to duty cycle. The minimum pulse width applies to both active and inactive states; 0% and 100% duty cycles are supported.

Table 15-6 shows restrictions to period and pulse width.
