ERR0STATUS, Error Record Primary Status Register
The ERR0STATUS contains information about the error record.
The register indicates:
- Whether any error has been detected.
- Whether any detected error was not corrected and returned to a master.
- Whether any detected error was not corrected and deferred.
- Whether a second error of the same type was detected before software handled the first error.
- Whether any error has been reported.
- Whether the other error record registers contain valid information.
NoteIn Lock mode, this register is RAZ.
Bit field descriptions
ERR0STATUS is a 32-bit register.
Figure B3-8 ERR0STATUS bit assignments
- AV, 
Address Valid. The possible values are:
ERR0ADDR is not valid.
ERR0ADDR contains an address associated with the highest priority error recorded by this record.
- V, 
Status Register valid. The possible values are:
ERR0STATUS is not valid.
ERR0STATUS is valid. At least one error has been recorded.
- UE, 
- Uncorrected error. The possible values are:
No error that could not be corrected or deferred has been detected.
At least one error that could not be corrected or deferred has been detected. If error recovery interrupts are enabled, then the interrupt signal is asserted until this bit is cleared.
- ER, 
- Error reported. The possible values are:
No external abort has been reported.
The node has reported an external abort to the master that is in access or making a transaction.
- OF, 
- Overflow. The possible values are:
- If UE == 1, then no error status for an Uncorrected error has been discarded.
- If UE == 0 and DE == 1, then no error status for a Deferred error has been discarded.
- If UE == 0, DE == 0, and CE !==
The corrected error counter has not overflowed.
More than one error has occurred and so details of the other error have been discarded.
- MV, 
- Miscellaneous Registers Valid. The possible values are:
ERR0MISC0 and ERR0MISC1 are not valid.
This bit indicates that ERR0MISC0 contains additional information about any error that is recorded by this record.
- CE, [25:24]
- Corrected error. The possible values are:
No corrected error recorded.
At least one corrected error recorded.
- DE, 
- Deferred error. The possible values are:
No errors were deferred.
At least one error was not corrected and deferred by poisoning.
- PN, 
Poison. The value is:
The Cortex®‑A76AE core cannot distinguish a poisoned value from a corrupted value.
- UET, [21:20]
- Uncorrected Error Type. The value is:
- SERR, [4:0]
- Primary error code. The possible values are:
Errors due to fault injection.
ECC error from internal data buffer.
ECC error on cache data RAM.
ECC error on cache tag or dirty RAM.
Parity error on TLB data RAM.
Error response for a cache copyback.
Deferred error from slave not supported at the consumer. For example, poisoned data received from a slave by a master that cannot defer the error further.
There are no configuration notes.
