ERXMISC3: Selected Error Record Miscellaneous Register 3

Purpose

Accesses bits [63:32] of ERR<n>MISC1 for the error record <n> selected by ERRSELR.SEL.

Configuration

AArch32 System register ERXMISC3 bits [31:0] are architecturally mapped to AArch64 System register ERXMISC1_EL1[63:32].

This register is present only when FEAT_RAS is implemented. Otherwise, direct accesses to ERXMISC3 are UNDEFINED.

Attributes

ERXMISC3 is a 32-bit register.

Bits [63:32] of ERR<n>MISC1

Bits [31:0]

ERXMISC3 accesses bits [63:32] of ERR<n>MISC1, where <n> is the value in ERRSELR.SEL.

Accessing ERXMISC3

If ERRIDR.NUM is 0x0000 or ERRSELR.SEL is greater than or equal to ERRIDR.NUM, then one of the following occurs:

ERR<n>MISC1 describes additional constraints that also apply when ERR<n>MISC1 is accessed through ERXMISC3.

Accesses to this register use the following encodings in the System register encoding space:

MRC{<c>}{<q>} <coproc>, {#}<opc1>, <Rt>, <CRn>, <CRm>{, {#}<opc2>}
