In conjunction with TRCCLAIMCLR, provides Claim Tag bits that can be separately set and cleared to indicate whether functionality is in use by a debug agent.
For additional information, see the CoreSight Architecture Specification.
External register TRCCLAIMSET bits [31:0] are architecturally mapped to AArch64 System register TRCCLAIMSET[31:0].
This register is present only when FEAT_ETE is implemented and FEAT_TRC_EXT is implemented. Otherwise, direct accesses to TRCCLAIMSET are RES0.
The number of claim tag bits implemented is IMPLEMENTATION DEFINED. Arm recommends that implementations support a minimum of four claim tag bits, that is, SET[3:0] reads as 0b1111.
TRCCLAIMSET is a 32-bit register.

Claim Tag Set. Indicates whether Claim Tag bit <m> is implemented, and is used to set Claim Tag bit <m> to 1.
SET[<m>] | Meaning |
---|---|
0b0 | On a read: Claim Tag bit <m> is not implemented. On a write: Ignored. |
0b1 | On a read: Claim Tag bit <m> is implemented. On a write: Set Claim Tag bit <m> to 1. |
This bit reads-as-zero and ignores writes if m > the number of Claim Tag bits.
Access to this field is RAO/W1S.
