24. Usage Notes
24.11 Programmable I/O Ports
• Pins P7_2 to P7_5, P8_0, and P8_1 have the forced cutoff function of the three-phase PWM output. When
these ports are set in output mode (port output, timer output, three-phase PWM output, serial interface output),
they are affected by the three-phase motor control timer function and the NMI pin setting. Table 24.5 shows
the INVC0 register setting, NMI pin input level, and output pin states.

NOTE:
1. The INV03 bit becomes 0 after a low-level (“L”) signal is applied to the NMI pin.
• The availability of the pull-up resistors is undefined until the internal power voltage stabilizes even if the
RESET pin is held “L”.
