Function

Uncorrectable memory bit error flag (GCCTL1.UBDIFG) does not trigger NMI

Description

The GCCTL1.UBDIFG flag is an interrupt flag that gets set if an uncorrectable bit error has been detected in non-volatile memory. Even the GCCTL1.UBDIFG flag is set to 1 (GCCTL0.UBDRSTEN = 0 and GCCTL0.UBDIE = 1), it does not trigger a NMI request. In this case, the application is not notified via a NMI request that an uncorrectable bit error occurred in non-volatile memory (SYSSNIV = 0).

Workaround

Set GCCTL0.UBDRSTEN = 1 and GCCTL0.UBDIE = 0 to trigger a PUC and check GCCTL1.UBDIFG = 1 after each PUC for manual interrupt flag handling.
Please consider GC4 errata for side effects.
