I am working on MPC5777C.
The errata e9570 of FCCU which mentions "FOSU may assert reset when a hardware recoverable fault of width less than one safe clock period occurs"
The workaround mentioned for this errata are
- Program “Request reset pulse” in the associated FCCU Non-Critical Fault State Configuration (FCCU_NCFS_CFGn) register for that hardware recoverable fault in addition to the EOUT signaling.
- Alternatively, if the reset reaction is not desired, configure the fault as software recoverable.
As a third workaround can the ALARAM interrupt be used with configurable time out in FCCU_NCF_TO.?
As the errata says “hardware recoverable fault of width less than one safe clock period”, this time can be programmed in FCCU_NCF_TO register to avoid the fault situation.
Is this approach can be used as workaround for this errata.?
