Fault Source ID Register
The SEC fault source ID register (SEC_FSID) contains a fault source ID and internal/external fields.
NOTE:These bits are not reset by system reset so that a fault that automatically triggers a system reset to avoid a
fault may be analyzed after the reset occurs.

Fault External.
The SEC_FSID.FEXT bit indicates that the last active fault was asserted by an exter-
nal device. The SEC sets the SEC_FSID.FEXT bit when the SEC_FSTAT.ACT bit
is set by the fault input pins. The SEC_FSID.FEXT bit is cleared when the
SEC_FSTAT.ACT bit is set by an internal fault or when the external fault is ended.
When the SEC_FSID.FEXT bit is set, the SEC_FSID.SID is cleared.
Source ID.
The SEC_FSID.SID identifies the fault assertion detected by the SEC fault inter-
face. The SEC loads the SEC_FSID.SID field value when a system fault indication
is asserted. The SEC fault interface does not change the SEC_FSID.SID value until
the fault is no longer pending or active, as indicated by the SEC_FSTAT.PND bit
and SEC_FSTAT.ACT bit being cleared in the
