R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 2-0 PCLKDIV<2:0>: PWM Input Clock Prescaler (Divider) Select bits
(1)
111 = Reserved
110 = Divide by 64, maximum PWM timing resolution
101 = Divide by 32, maximum PWM timing resolution
100 = Divide by 16, maximum PWM timing resolution
011 = Divide by 8, maximum PWM timing resolution
010 = Divide by 4, maximum PWM timing resolution
001 = Divide by 2, maximum PWM timing resolution
000 = Divide by 1, maximum PWM timing resolution (power-on default)
Note 1: These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
Note: The PWM input clock prescaler will affect all timing parameters of the PWM module, including period, duty
cycle, phase, dead-time, triggers, leading-edge blanking and PWM capture.
