Description
11-0
PWM0D[11:0]
12-bit PWM duty registers
If PWM0P
≤ PWM0D,
PWM0 outputs high level when the PWM0S bit is set to “0”.
PWM0 outputs GND level when the PWM0S bit is set to “1”.
If PWM0D = 00H,
PWM0 outputs GND level when the PWM0S bit is set to “0”.
PWM0 outputs high level when the PWM0S bit is set to “1”.

Description
11-0
PWM2D[11:0]
12-bit PWM duty registers
If PWM2P
≤ PWM2D,
PWM2 outputs high level when the PWM2S bit is set to “0”.
PWM2 outputs GND level when the PWM2S bit is set to “1”.
If PWM2D = 00H,
PWM2 outputs GND level when the PWM2S bit is set to “0”.
PWM2 outputs high level when the PWM2S bit is set to “1”.
Note: The change of PWMxDH will take affect at the next PWMx period. The user must change PWMxDL at first, and then
change PWMxDH for changing PWMx duty.
