6.2 PFSM Triggers

There are various triggers that can enable a state transition between configured states. Table 6-1 describes each trigger and its associated state transition from highest priority (Immediate Shutdown) to lowest priority. Active triggers of higher priority block triggers of lower priority and the associated sequence.
