Description
Critical fault state configuration
00: No reset reaction
01: Short functional reset (FAULT state reaction)
10: Long functional reset (FAULT state reaction)
11: No reset reaction
This register can be read and written by the software.
22.6.7 FCCU NCFS Configuration Register (FCCU_NCFS_CFG0..7)
The FCCU_NCF_FS_CFGx register is accessible in write mode only in the CONFIG state. It contains the
configuration of each non-critical fault in terms of fault reaction (short or long ‘functional’ reset) when it
is the root cause for the FAULT state transition.
Offset: 0x04C–0x068 (8 registers)

22.6.8 FCCU CF Status Register (FCCU_CFS0..3)
The FCCU_CFSx register contains the latched fault indication collected from the critical fault sources.
Faults are latched even if the FCCU is in the CONFIG state and independently from the enabling or
reactions programmed for the CF.
No reactions are executed until the FCCU moves in the NORMAL state. FCCU reacts and moves from the
NORMAL or ALARM state into the FAULT state if a critical fault is triggered. The status bits of the
