Hello,

Since you didnt share device you are refering to, I will answer generally.

You have status bit for lock step core in SSCM module SSCM_UOPS register:

I am bit confused what you want to achieve, could you please explain it in details?

Best regards,

Peter

Hello,

If you want to trigger interrupt on FCCU fault.

1. Enable the ALARM timeout in the NCF_TOEn register.
2. Enable the reaction on fault in the NCF_En register.
3. Enable the alarm interrupt in the IRQ_ALARM_ENn register.

You can refer to :

https://www.nxp.com/docs/en/application-note/AN5284.pdf

Then configure INTC module and interrupt routines according to reference manual for this particular interrupt.

Best regards,

Peter
