3.2.3 External Enable
The External Enable functionality is summarized in Table 21:
Table 21 External Enable Function Overview
Parameter
Short Description
Function
External Enable.
Periodicity
Invalid signal on EN pin.
Action in case of failure event 1. Emergency (Regular) Turn-off Sequence.
2. Error Flag PER.ENER is set.
3. Assertion of signal NFLTA.
Programmability
No.
In-System Testability
Yes.
The functionality of the signal at pin EN is given in Chapter 2.4.8. In case of a Valid-to-Invalid signal transition,
an error is detected. In this case, an Emergency (Regular) turn-off sequence is initiated, bit PER.ENER is set and
a fault notification is issued on pin NFLTA (in case of an OPM transition the state machine - see Chapter 2.4.7).
The current validity state of the signal at pin EN can be read on bit PSTAT2.ENVAL.
This function can be tested by generating an invalid signal on pin EN and verifying that the actions done by the
device correspond to the expected behavior.
