CLR ALM
Clear Alarm Bit. This bit reads as a 0. Writing this bit to a 1 unlatches the active ALARM output, set-
ting the ALARM pin to its inactive state if the alarm condition is no longer present. If the alarm condi-
tion persists, the ALARM pin once again asserts to its active state.

EVENT
This bit indicates the status of the EVENT pin’s logic level, detected after the tG glitch filter time.
1
EVENT AF
Default value = 0. If the value in the Event Counter SRAM value is greater than or equal to the Event
Counter Alarm Limit value, then this bit is automatically set to a value of 1 to indicate an ALARM
event. When the EVENT SRAM Counter value is less than the Event Counter Alarm Limit, this bit
automatically set to a value of 0, indicating that there is no EVENT alarm.
0
ETC AF
Default value = 0. If the value in the ETC SRAM value is greater than or equal to the ETC Alarm Limit
value, then this bit is automatically set to a value of 1 to indicate an ALARM event. When the ETC
SRAM value is less than the ETC Alarm Limit, this bit automatically set to a value of 0, indicating that
there is no ETC alarm.
