7.3.5.1 Interrupt and Trigger Mode

With ALERT_MODE at default value of 0b, the ALERT output can be configured to generate an interrupt signal for microcontroller when a user-defined event occurs. A user-defined event can be a conversion completion or an error from diagnostic tests. The ALERT pin can also be used in this mode to trigger a conversion start using the TRIGGER_MODE register bit.
