SLAS986D November 2014 – February 2018 AMC7836
The AMC7836 device continuously monitors all general purpose analog inputs and local temperature sensor during normal operation. When any input is out of the specified range N consecutive times, the corresponding alarm bit is set (1). If the input returns to the normal range before N consecutive times, the corresponding alarm bit remains clear (0). This configuration avoids any false alarms. When an alarm status occurs, the corresponding alarm bit is set (1). When the corresponding bit in the ALARMOUT Source Registers is cleared (0), the ALARMOUT pin is latched.
Whenever an alarm status bit is set, it remains set until the event that caused it is resolved and its status register is read. Reading the Alarm Status Registers clears the alarm status bits. The alarm bit can only be cleared by reading its Alarm Status register after the event is resolved, or by hardware reset, software reset, or power-on reset. All alarm status bits are cleared when reading the Alarm Status registers, and all these bits are reasserted if the out-of-limit condition still exists after the next conversion cycle, unless otherwise noted.
