îš„ Fault Trace: U2
User constants for error tracing are shown in the following table.
Note 1. The following faults are not included in the fault trace: CPF00, 01, 02, 03, UV1, and UV2.
2. If the PUF fault is already indicated in U2-xx or U3-xx, even if the PUF fault is detected again, the fault trace is not updated. (SPEC: E or later only)
