3. Operations 
 
3.1.  PPG circuit operations 
The PPG module can output pulse signals having arbitary cycle and duty ratio. 
The pulse output can be controlled based on the timer operation. 
 PPG functions 
The PPG timer starts decrem enting the down counter value being set in the LOW width reload register by 
triggered. During this time, the output is set to LOW.  After an underflow occurs, the output is inverted to 
HIGH. Then, the PPG timer starts decrementing the value being set in the HIGH width...
