HD3SS3220: Interruption issues with chips

Part Number: HD3SS3220

.23 pin, after the interrupt is triggered, is this bit written to clear the interrupt and raise the interrupt pin.

    Hi Tony,

    When an interrupt occurs, this register bit will go high and the INT pin will be pulled low. Your application should eventually clear the bit (write 0). This would stop INT from being pulled to GND, but would not in-itself raise the pin. From the datasheet, the INT_N pin is open-drain, and does not have an internal pull up resistor.

    Best,

    Shane
