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?

[DPate.1133]

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.
