Description

7–6

Reserved, should be cleared.

ER1BR

Enable RAM 1-bit Reporting.

0 Reporting of single-bit RAM corrections is disabled.

1 Reporting of single-bit RAM corrections is enabled.

This bit can only be set if the SoC-configurable input enable signal is asserted. The occurrence of a

single-bit RAM correction generates a MCM ECC interrupt request as signalled by the assertion of

ESR[R1BC]. The address, attributes and data are also captured in the REAR, RESR, REMR, REAT and

REDR registers.

EF1BR

Enable Flash 1-bit Reporting.

0 Reporting of single-bit flash corrections is disabled.

1 Reporting of single-bit flash corrections is enabled.

This bit can only be set if the SoC-configurable input enable signal is asserted. The occurrence of a

single-bit flash correction generates a MCM ECC interrupt request as signalled by the assertion of

ESR[F1BC]. The address, attributes and data are also captured in the FEAR, FEMR, FEAT and FEDR

registers.

3–2

Reserved, should be cleared.

ERNCR

Enable RAM Non-Correctable Reporting.

0 Reporting of non-correctable RAM errors is disabled.

1 Reporting of non-correctable RAM errors is enabled.

The occurrence of a non-correctable multi-bit RAM error generates a MCM ECC interrupt request as

signalled by the assertion of ESR[RNCE]. The faulting address, attributes and data are also captured in

the REAR, RESR, REMR, REAT and REDR registers.

EFNCR

Enable Flash Non-Correctable Reporting.

0 Reporting of non-correctable flash errors is disabled.

1 Reporting of non-correctable flash errors is enabled.

The occurrence of a non-correctable multi-bit flash error generates a MCM ECC interrupt request as

signalled by the assertion of ESR[FNCE]. The faulting address, attributes and data are also captured in

the FEAR, FEMR, FEAT and FEDR registers.
