where pins RTP0
used as a pulse output trigger (pulse mode 1 of pulse output port 0). Note that when using interrupts, set
up to enable the interrupts. For details, refer to “CHAPTER 6. INTERRUPTS.” The above setting example
is also applied to the case of pulse output port 1. Each right side of Figures 9.4.1 to 9.4.5 shows registers
used in pulse output port 1.
