1. When using pulse output port 0, be sure to set the relevant registers after setting the waveform output select bits
2. When using pulse output port 1, be sure to set the relevant registers after setting the waveform output select bits
3. When performing the pulse width modulation in pulse output port 0, be sure to use timers A1, A2, A4 in the pulse
4. When performing the pulse width modulation in pulse output port 1, be sure to use timers A6, A7, A9 in the pulse
5. Note that, when not making the pulse output inactive by input of a falling edge to pin P6OUT
