3. INT pin output
The output source of INT pin is ORed between ADETL/R bits and VDET bit If the output source of INT pin is “H”, INT
pin=“L”, and if the output source of INT pin is “L”, INT pin=“Hi-Z”. If each mask bit is “1”, each detection bit is masked
independently and the detection result isn’t reflected to INT pin.
