Field

NCFCx

Non-critical fault configuration

0: HW recoverable fault

1: SW recoverable fault

Description

The non-critical fault configuration defines the fault recovery mode.

HW recoverable faults are self recovered (status flag clearing and related) if the root cause has

been removed.

SW recoverable faults are recovered (status flag clearing) by SW clearing of the related status

flag.

This register can be read and written by the software.

22.6.6 FCCU CFS Configuration Register (FCCU_CFS_CFG0..7)

The FCCU_CF_FS_CFGx register is accessible in write mode only in the CONFIG state. It contains the

configuration of each critical fault in terms of fault reaction (short or long âfunctionalâ reset) when it is the

root cause for the FAULT state transition.
