EX1: Since the first trigger type is a falling edge after the PPG starts, the PPG timer is triggered by a falling edge until
the PPG stops.
EX2: Since the first trigger type is a raising edge after the PPG starts, the PPG timer is triggered by a raising edge un-
til the PPG stops.
PPG0C: CMP1EN, CMP0EN comparator enable/disable bits
Bits2~4 of the PPG0 control register, PPG0C, can be used to define the pre-scaling stages of the PPG0 timer counter
clock.
