14.11 PWM Power-down/Wakeup Procedures
The following flow diagrams describe the possible pwm procedures users require to take care prior to
the product power-down/wake-up. The power-down procedure below will result in PWM output a low
state after power-down. To output a high state, users may set PWMn to FFFh and initial state set to
high through option bit (EPOL/OPOL).
