Bits Name Function
[31:16] - Reserved, RAZ.
[15] RP

Repeat corrected error count:

0 = The GIC-600 does not implement a repeat corrected error counter.

[14:12] CEC

Corrected error count:

0b000 = The GIC-600 does not implement a standard Corrected error counter in GICT_ERR<n>MISC0.

[11:10] CFI

Corrected errors fault interrupt. Depending on the configuration, returns either:

0b00 = The GIC-600 does not provide a fault handling interrupt for corrected errors.

0b10 = The GIC-600 provides a controllable fault handling interrupt for corrected errors.

[9:8] UE

Uncorrected error. Depending on the configuration, returns either:

0b00 = The GIC-600 does not provide an in-band uncorrected error reporting.

0b10 = The GIC-600 provides a controllable in-band uncorrected error reporting.

[7:6] FI

Fault handling interrupt for uncorrected errors. Depending on the configuration, returns either:

0b00 = The GIC-600 does not provide a fault handling interrupt.

0b10 = The GIC-600 provides a controllable fault handling interrupt.

[5:4] UI

Error recovery interrupt for uncorrected errors. Depending on the configuration, returns either:

0b00 = The GIC-600 does not provide an error recovery interrupt for uncorrected errors.

0b10 = The GIC-600 provides a controllable error recovery interrupt for uncorrected errors.

[3:2] DE

Deferring of errors support:

0b00 = The GIC-600 does not support the deferring of errors.

[1:0] ED

Uncorrected error reporting:

0b01 = Uncorrected error reporting is always enabled.
