3.4.4 Over Current Detection Interrupt Process

The overcurrent detection interrupt is an interrupt that occurs when either an external overcurrent detection
signal is input at POEG pin, or an output short circuit is detected by the GTETRGD output level comparison
operation. In both cases, the PWM output terminal are put in the high impedance state. Therefore, at the
start of execution of this interrupt processing, the PWM output terminal is already in the high impedance
state and the output to the motor had been stopped.
