Note
The one-shot pulse output function is used to make a pulse output level active by software and inactive by hardware
(interrupt request signal).
This function is different from the one-shot timer function of timer/event counter 2 in nature.
The outline of the serial interface is as follows (for details, refer to CHAPTER 17 OUTLINE OF SERIAL INTERFACE).
