Safety Modules: Incorrect Reporting of ECC_GRP, ECC_BIT and ECC_TYPE Information for Functional Safety Errors
For functional safety errors, the logged information - ECC_GRP, ECC_BIT, and ECC_TYPE in the Error Status Registers may be incorrect for certain safety checkers. This only applies to safety checkers that map to ECC_GRP = 0,15,31,47,63...(N*16-1). In the case for the DDR Bridge/Controller, the issue only applies to the safety checkers where ECC_GRP = 0,31,63...(N*32-1).
This issue affects all Safety Module instances and their sub-banks. Refer to section Safety Modules of the device TRM.
Note: The detection and interrupt signaling of these safety errors is unaffected. Only the logging of the aforementioned fields of the Error Status Registers are affected.
None. For these specific safety checkers, software is limited to knowing whether a correctable or uncorrectable error occurred and which Safety Module instance had the error (thus knowing the IP module), but not which exact safety checker encountered the error.
