[Precautions for three-phase waveform mode]
1. When using the three-phase waveform mode, be sure to fix the waveform output select bits (bits 2 to 0
at address A616) to “100 ,” and then, set the relevant registers.
When not using pulse output port 0 and three-phase waveform mode, be sure to fix the waveform
output select bits (bits 2 through 0 at address A616) to “000 .”

2. When not inactivating the three-phase waveform output by using a falling edge input to pin P6OUTCUT
be sure to connect pin P6OUTCUT to Vcc via a resistor.

3. While the fixed level is output, be sure not to change the value of the U/V/W-phase fixed output’s polarity
set bit (bits 2 through 0 at address A916).
