11.4.3. Debug Claim Tag Set register

The DBGCLAIMSET_EL1characteristics are:

Purpose

Used by software to set CLAIM bits to 1.

Usage constraints

This register is accessible as follows:

EL0

EL1

(NS)

EL1

(S)

EL2

EL3

(SCR.NS = 1)

EL3

(SCR.NS = 0)

-RWRWRWRWRW
Configurations

DBGCLAIMSET_EL1 is architecturally mapped to:

  • The AArch32 register DBGCLAIMSET.

  • The external register DBGCLAIMSET_EL1.

Attributes

DBGCLAIMSET_EL1 is a 32-bit register.

Figure 11.2 shows the DBGCLAIMSET_EL1 bit assignments.

Table 11.4 shows the DBGCLAIMSET_EL1 bit assignments.

Table 11.6. DBGCLAIMSET_EL1 bit assignments
BitsNameFunction
[31:8]-

Reserved, res0.

[7:0]CLAIM

Claim set bits.

Writing a 1 to one of these bits sets the corresponding CLAIM bit to 1. This is an indirect write to the CLAIM bits.

A single write operation can set multiple bits to 1. Writing 0 to one of these bits has no effect.


To access the DBGCLAIMSET_EL1 in AArch64 Execution state, read or write the register with:

MRS <Xt>, DBGCLAIMSET_EL1 ; Read DBGCLAIMSET_EL1 into XtMSR DBGCLAIMSET_EL1, <Xt> ; Write Xt to DBGCLAIMSET_EL1

The DBGCLAIMSET_EL1 can be accessed through the internal memory-mapped interface and the external debug interface, offset 0xFA0.
