PWMxD

PWM duty

Note

(0 * clock cycle) / TCP2 timer’s period

All off

(1 * clock cycle) / TCP2 timer’s period

(2 * clock cycle) / TCP2 timer’s period

……

((n) * clock cycle) / TCP2 timer’s period

……

TCP2D

((TCP2D) * clock cycle) / TCP2 timer’s period

All on

Note: 1. PWMxD can not bigger than TCP2D

2. TCP2 timer’s period = (TCP2D) * clock cycle.

3. PWM can start 0 or start 1 by mask option.
