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.

[S32G2 Reference Manual, Rev. 8, February 2024, page 3896]

Hi @carlos_o 

Thanks for the info!

so, which means this register should be checked in cyclic to find the reported fault right?

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
