CTICLAIMSET, CTI Claim Tag Set register

The CTICLAIMSET characteristics are:


Used by software to set CLAIM bits to 1.


CTICLAIMSET is in the Debug power domain. Some or all RW fields of this register have defined reset values. These apply only on an External debug reset. The register is not affected by a Warm reset and is not affected by a Cold reset.

Implementation of this register is OPTIONAL.


CTICLAIMSET is a 32-bit register.

Field descriptions

The CTICLAIMSET bit assignments are:

CLAIM[<x>], bit [x]

CLAIM[<x>], bit [x], for x = 0 to 31

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:


No action.


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:


This interface is accessible as follows:

  • When SoftwareLockStatus() accesses to this register are RO.
  • When !SoftwareLockStatus() accesses to this register are RW.
