Value (H) Description
The PWM deadband (PWMDB) register (see
value. The deadband value determines the number of PWM input cycles to use for the
deadband time for complementary PWM output pairs. When counting PWM input cycles,
the PWM input signal is used directly (no prescaler). The minimum deadband value is 1.
Maximum deadband time is programmed by setting a value of
only once following a System Reset event. All other writes are ignored.
The value in the PWMMPF register determines the minimum width pulse, either high or
low, generated by the PWM module. The minimum pulse width period is calculated as:
PWMMPF—Minimum Pulse Filter
Sets the minimum allowed output pulse width in PWM clock cycles.
