TDA7577, PIN16 pin is left floating to disable I2C bus mode, the speaker short-circuit fault is detected, PIN14-CD_OUT output is permanently low, and the fault still exists after power-on again, and the speaker is in no sound output protection state. May I ask TDA7577 in the I2C disabled mode, How to clear faults through hardware control and restore normal operation?
