Debug CLAIM Tag Set register
Used by software to set the CLAIM tag bits to 1.
The architecture does not define any functionality for the CLAIM tag bits.
CLAIM tags are typically used for communication between the debugger and target software.
Used in conjunction with the DBGCLAIMCLR register.
AArch32 System register DBGCLAIMSET bits [31:0] are architecturally mapped to AArch64 System register DBGCLAIMSET_EL1[31:0].
AArch32 System register DBGCLAIMSET bits [31:0] are architecturally mapped to AArch64 System register DBGCLAIMCLR_EL1[31:0].
AArch32 System register DBGCLAIMSET bits [31:0] are architecturally mapped to AArch32 System register DBGCLAIMCLR[31:0].
AArch32 System register DBGCLAIMSET bits [31:0] are architecturally mapped to External register DBGCLAIMSET_EL1[31:0].
AArch32 System register DBGCLAIMSET bits [31:0] are architecturally mapped to External register DBGCLAIMCLR_EL1[31:0].
This register is present only when FEAT_AA32EL1 is implemented. Otherwise, direct accesses to DBGCLAIMSET are UNDEFINED.
An implementation must include eight CLAIM tag bits.
DBGCLAIMSET is a 32-bit register.

Claim Tag Set. Used to set Claim Tag bit <m> to 1.
| CLAIM<m> | Meaning |
|---|---|
| 0b0 |
On a write: Ignored. |
| 0b1 |
On a write: Set Claim Tag bit <m> to 1. |
Access to this field is RAO/W1S.
