The DBGCLAIMSET_EL1 characteristics are:
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_EL1 register.
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 8 CLAIM tag bits.
DBGCLAIMSET_EL1 is a 32-bit register.
The DBGCLAIMSET_EL1 bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | CLAIM |
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.
Set CLAIM tag bits. 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.
