DBGCLAIMSET_EL1, Debug CLAIM Tag Set register

The DBGCLAIMSET_EL1 characteristics are:

Purpose

Used by software to set the CLAIM tag bits to 1.

The architecture does not define any functionality for the CLAIM tag bits.

Used in conjunction with the DBGCLAIMCLR_EL1 register.

Configuration

External register DBGCLAIMSET_EL1 bits [31:0] are architecturally mapped to AArch64 System register DBGCLAIMSET_EL1[31:0] .

External register DBGCLAIMSET_EL1 bits [31:0] are architecturally mapped to AArch32 System register DBGCLAIMSET[31:0] .

DBGCLAIMSET_EL1 is in the Core power domain.

An implementation must include eight CLAIM tag bits.

Attributes

DBGCLAIMSET_EL1 is a 32-bit register.

Field descriptions

The DBGCLAIMSET_EL1 bit assignments are:

Bits [31:8]

Reserved, RAZ/SBZ. Software can rely on these bits reading as zero, and must use a should-be-zero policy on writes. Implementations must ignore writes.

CLAIM, bits [7:0]

Set CLAIM tag bits.

This field is RAO.

Writing a 1 to one of these bits sets the corresponding CLAIM tag bit to 1. This is an indirect write to the CLAIM tag bits. A single write operation can set multiple CLAIM tag bits to 1.

Writing 0 to one of these bits has no effect.

Accessing the DBGCLAIMSET_EL1

DBGCLAIMSET_EL1 can be accessed through the external debug interface:

This interface is accessible as follows:

• When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus() and SoftwareLockStatus() accesses to this register are RO.
• When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus() and !SoftwareLockStatus() accesses to this register are RW.
• Otherwise accesses to this register generate an error response.
