PWM Deadband Register
PWM Minimum Pulse Width Filter
7
The PWM Deadband (PWMDB) register
value. This register determines the number of system clock cycles inserted as dead-time in
complementary output mode. The minimum deadband value is 1.
The value in the PWM Minimum Pulse Width Filter (PWMMPF) register
determines the minimum width pulse, either High or Low, which can be generated by the
PWM module. The minimum pulse width period is calculated as:

Description
PWM Dead band
Sets the PWM dead band period for which both PWM outputs of a
complementary PWM output pair are deasserted.
=
PWM Prescaler
The prescaler divides down the PWM input clock (either the system
clock or the PWMIN external input). This field is buffered. Changes to
this field take effect at the next PWM reload event. Reads always return
the values from the temporary holding register.
