GPI Fault Enable must be set to enable this feature. When set, if there is no fault on a Fault Bus, the Fault Pin is digital input pin and listen to the Fault Bus. When one or multiple UCD90160A devices detect a rail fault (see Table 7-7), the corresponding Fault Pin is turned into active driven low state, pulling down the Fault Bus and informing all other UCD90160A devices of the corresponding fault. This way, a coordinated action can be taken across multiple devices. After the fault is cleared, the state of the Fault Pin is turned back to an input pin.
