Critical fault key = 0xAB3498FE
Description
22.6.12 FCCU NCF Enable Register (FCCU_NCFE0..3)
The FCCU_NCFEx register enables the critical fault sources to allow a transition from the NORMAL into
the FAULT or ALARM state. In case of fault masking, the respective status bit into the FCCU_NCFSx
register is anyway set (for debugging purposes), only the reaction is masked.
The FCCU_NCFEs register is accessible in write mode only in the CONFIG state.
