In SPC56EL60 critical fault LVD/HVD Bist failure is configured in FCCU CFS configuration register to no reset reaction. however when i inject this fault trough fake fault register by writing 21 in them , Reset is happening. could you clarify it?

according to me it should not lead to reset as in FCCU CFS config register it not configured to perform reset reaction for this critical fault.

Hello ,

Have you set correctly Register FCCU CF Configuration Register (FCCU_CF_CFG0) CFC21 by 0 ?

For your information ,

have you checked SPC56ELxx_RLA FCCU Test Application for DiscoveryPlus ?

Are you in SAFE mode ?

Best regards

Hello,

Thanks for answer!

The configuration of FCCU is as follow.

FCCU_CF_CFG0 = 0xFFFFFFFFUL

FCCU.CFS_CFG[0] = 0xAAAAAAAAUL //Reset for all Critical fault 0 to 15

FCCU.CFS_CFG[1] = 0xAAAA0000UL // No reset for 16 to 23 critical fault and reset for 24 to 31 critical fault.

also i have check by setting both FCCU.CFS_CFG to 0 , still it is causing reset when 21th critical fault injected through fake fault register.
