Bits Name Function
[31] AV

Indicates if the address is valid:

0 = GICT_ERR<n>ADDR is not valid.

1 = GICT_ERR<n>ADDR contains an address that is associated with the highest priority error that this record stores. Only present in record 0.

Indicates if this register is valid:

0 = GICT_ERR<n>STATUS is not valid.

1 = GICT_ERR<n>STATUS is valid. One or more errors are recorded.

[29] UE

Uncorrectable error bit.

SBZ in Correctable Error (CE) records.

[28] ER

Indicates that at least one error has been reported over ACE-Lite.

Set for record 0 only, and only for accesses to corrupted data, and bad incoming access.

[27] OF Record has overflowed.
[26] MV

Indicates if the GICT miscellaneous registers are valid:

0 = GICT_ERR<n>MISC0 and GICT_ERR<n>MISC1 are not valid.

1 = GICT_ERR<n>MISC0 and GICT_ERR<n>MISC1 are valid.

[25:24] CE

Correctable Error. Indicates errors that are correctable as shown in Table   4-45 Error records:

0b00 = No CE recorded.

0b10 = At least one CE recorded.

[23:22] - Reserved, RAZ/WI.
[21:20] UET

RES0 unless UE == 1, in which case:

0b10 = UEO.

0b11 = UER.
[19:16] - Reserved, RAZ/WI.
[15:8] IERR

implementation-defined error code:

Returns information shown in Table   4-51 Data field encoding.

This field is RO in Record 0 apart from Record 0.
