Table 51. PWM Minimum Pulse Width Filter (PWMMPF)
Table 52. PWM Fault Mask Register (PWMFM)
The value in the PWM Minimum Pulse Width Filter (PWMMPF) Register, shown in Table
51, determines the minimum width pulse, either high or low, that can be generated by the
PWM module. The minimum pulse width period is calculated as:
The PWM Fault Mask (PWMFM) Register, shown in Table 52, enables individual fault
sources. PWM behaviour when an input is asserted is determined by the PWM Fault Con-
trol Register (PWMFCTL).

A Value other than 00H must be written to the PWMMPF registor or the PWM output
waveform will be distorted!
