Overcurrent diagnosis:
In case of an overcurrent event the corresponding status bit is set and the output driver is disabled.
If the overcurrent recovery enable bit is set, the output is automatically reactivated after a delay time
resulting in a PWM modulated current with a programmable duty cycle.
If the overcurrent recovery bit is not set, the microcontroller has to clear the overcurrent bit to
reactivate the output driver.
