Over Current Detection Interrupt Process - Renesas RA6T2 Application Note

Sensorless vector control for permanent magnetic
synchronous motor - 1shunt current detection

3.4.4 Over Current Detection Interrupt Process

The overcurrent detection interrupt is an interrupt that occurs when an external overcurrent detection signal
is input. 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.
