9.3 Setting of pulse output port mode
Figures 9.3.1 to 9.3.5 show an initial setting example for registers relevant to the pulse output port mode,
where an underflow of timer A0 is used as a pulse output trigger (in pulse mode 1). Note that when using
interrupts, set up to enable the interrupts. For details, refer to “CHAPTER 6. INTERRUPTS.”
