CTICLAIMSET, CTI CLAIM Tag Set register
The CTICLAIMSET characteristics are:
Purpose
Used by software to set CLAIM bits to 1.
Configuration
CTICLAIMSET is in the Debug power domain.
Implementation of this register is OPTIONAL.
Attributes
CTICLAIMSET is a 32-bit register.
Field descriptions
The CTICLAIMSET 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 |
| CLAIM31 | CLAIM30 | CLAIM29 | CLAIM28 | CLAIM27 | CLAIM26 | CLAIM25 | CLAIM24 | CLAIM23 | CLAIM22 | CLAIM21 | CLAIM20 | CLAIM19 | CLAIM18 | CLAIM17 | CLAIM16 | CLAIM15 | CLAIM14 | CLAIM13 | CLAIM12 | CLAIM11 | CLAIM10 | CLAIM9 | CLAIM8 | CLAIM7 | CLAIM6 | CLAIM5 | CLAIM4 | CLAIM3 | CLAIM2 | CLAIM1 | CLAIM0 |
CLAIM<x>, bit [x], for x = 31 to 0
CLAIM tag set bit.
For values of x greater than or equal to the IMPLEMENTATION DEFINED number of CLAIM tags, this bit is 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.
For other values of x, the bit is RAO and the behavior on writes is:
| CLAIM<x> | Meaning |
|---|---|
| 0b0 |
No action. |
| 0b1 |
Indirectly set CLAIM[x] tag to 1. |
A single write to CTICLAIMSET can set multiple tags to 1.
An External Debug reset clears the CLAIM tag bits to 0.
Accessing the CTICLAIMSET
CTICLAIMSET can be accessed through the external debug interface:
| Component | Offset | Instance |
|---|---|---|
| CTI | 0xFA0 | CTICLAIMSET |
This interface is accessible as follows:
- When SoftwareLockStatus() accesses to this register are RO.
- When !SoftwareLockStatus() accesses to this register are RW.
