PPG
[PWM Mode]
In PWM mode, the PPG timer can output pulses continuously after an activation trigger signal is
detected.
The output pulse cycle can be controlled by changing the PCSR value, and the duty ratio can be
controlled by changing the PDUT value.
Note:
After data is written to PCSR, be sure to write data to PDUT.
