PMF Deadtime A Bits — The 12-bit value written to this register is the number of PWM clock cycles in
complementary channel operation. A reset sets the PWM deadtime register to a default value of 0x0FFF,
selecting a deadtime of 256-PWM clock cycles minus one bus clock cycle.
Note: Deadtime is affected by changes to the prescaler value. The deadtime duration is determined as follows:

value of dead time. For example: if the prescaler is programmed for a divide-by-two and the PMFDTMA is
set to five, then P = 2 and the deadtime value is equal to DT = 2
case exists when the P = 1, then DT = PMFDTMA.
