*1: The same interrupt control register as that for 16-bit PPG timer 0 is assigned to PWC timer 0.
*2: The same interrupt control register as that for 16-bit PPG timer 1 is assigned to 16-bit output compare channel 1 match.
*3: The same interrupt control register as that for 16-bit PPG timer 2 is assigned to 16-bit free-run timer zero detect.

■ EI
OS Function of the 16-bit PPG Timer
Since the 16-bit PPG timer has a circuit that coordinates with EI
PPG interrupt occurs.
However, EI
(ICR) do not use interrupts. For example, when 16-bit PPG timer 0 uses EI
compare channel 0 match must be disabled.
