ERXMISC0_EL1, Selected Error Record Miscellaneous Register 0

The ERXMISC0_EL1 characteristics are:

Purpose

Accesses ERR<n>MISC0 for the error record selected by ERRSELR_EL1.SEL.

Configuration

AArch64 System register ERXMISC0_EL1 bits [31:0] are architecturally mapped to AArch32 System register ERXMISC0[31:0] .

AArch64 System register ERXMISC0_EL1 bits [63:32] are architecturally mapped to AArch32 System register ERXMISC1[31:0] .

This register is present only when RAS is implemented. Otherwise, direct accesses to ERXMISC0_EL1 are UNDEFINED.

Attributes

ERXMISC0_EL1 is a 64-bit register.

Field descriptions

The ERXMISC0_EL1 bit assignments are:

Bits [63:0]

ERXMISC0_EL1 accesses ERR<n>MISC0, where n is the value in ERRSELR_EL1.SEL.

Accessing the ERXMISC0_EL1

If ERRIDR_EL1.NUM == 0 or ERRSELR_EL1.SEL is set to a value greater than or equal to ERRIDR_EL1.NUM, then one of the following occurs:

Accesses to this register use the following encodings:
