[Precautions for pulse output port mode]
1. When using the pulse output port mode, be sure to set the relevant registers after the pulse output port mode is
set by the waveform output select bits (bits 2 to 0 at address A616).
When not using the pulse output port mode and three-phase waveform mode, be sure to fix the waveform output
select bits (bits 2 to 0 at address A616) to “000 .”
2
2. When performing the pulse width modulation, be sure to use timers A1, A2, A4 in the pulse width modulation
mode. (Refer to section “7.6 Pulse width modulation (PWM) mode.”) Note that, from pin P2
pulse by timer A4 is output. When it is unnecessary to output a PWM pulse, be sure to clear bit 2 of the timer A4
mode register (address 5A16) to “0.” At this time, pin P2 can be used as a programmable I/O port pin.

3. Note that, when not making the pulse output inactive by input of a falling edge to pin P6OUTCUT, be sure to connect
pin P6OUTCUT to Vcc via a resistor.
