Output Protection Functions

Operating mode output has the following protection functions:
• Halting PWM output by external signal
The 6-phase PWM output pins can be placed in the high-impedance state automatically by
inputting a specified external signal. There are four external signal input pins. For details, see
section 11.8, Port Output Enable (POE).
• Halting MMT output when oscillation stops
The 6-phase PWM output pins are placed in the high-impedance state automatically when
stoppage of the clock input is detected. However, pin states are not guaranteed when the clock
is restarted.
