SENSE WARN		Sense lines excessive voltage drop warning (over
		2.5V and below 4V) start/stop.
CONF TEST		Confidence test (BIT) errors. NOTE: this condition
		has no negative transition.
FOLD BACK		Fold-Back mode activated/deactivated.
MODE CHNG		Current Mode activated/deactivated.
LOW CURR		Low Current Window Warning start/stop.
LOW VOLT		Low Voltage Window Warning start/stop.
HIGH CURR		High Current Window Warning start/stop.
HIGH VOLT		High Voltage Window Warning start/stop.

The Events Filtering Mechanism enables the user to filter out non critical events (e.g. Window Warning, Current limit etc.). Critical events (such as OVP) can not be filtered.

The Events Filtering Mechanism has separate filters for the positive and the negative transition generated events. For example: the occurrence of a current limit condition is a positive transition (the Power Module entered the current limit state) while the end of the current limit condition is the negative transition.

The “start” or “activated” indication in the above refers to a positive transition while the “stop” or “deactivated” indication refers to a negative transition.

The negative transition of the FOLD BACK and MODE CHNG events occur simultaneously. Therefore, when any of the relevant bits of the Negative Mask Register are set, the Power Module will generate an event as though both bits were set.
