Hi @Harish_R,

The registers you want to read is the 67.7.1.7 Non-critical Fault Status (NCF_S0 - NCF_S3) at the S32G2.

Hi @carlos_o

Thanks for the info!

Hi @Harish_R

It will depend on your configuration, because you can enable the FCCU to triggers an IRQ to solve the fault, if that happen the register clear the NCF fault at the register. You could review the flow of a fault in the Figure 591. Single fault signal flow

[S32G3 Reference Manual, Rev. 4, 02/2024, page 4126]

Also, keep in mind that you need to clear a software-recoverable non-critical faults
