# CTICLAIMCLR, CTI CLAIM Tag Clear register

The CTICLAIMCLR characteristics are:

## Purpose

Used by software to read the values of the CLAIM bits, and to clear CLAIM tag bits to 0.

## Configuration

CTICLAIMCLR is in the Debug power domain.

Implementation of this register is OPTIONAL.

## Attributes

CTICLAIMCLR is a 32-bit register.

## Field descriptions

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 clear bit.

Reads return the value of CLAIM<x>, writes have the following behavior:

CLAIM<x> | Meaning
--- | ---
0b0 | No action.
0b1 | Indirectly clear CLAIM<x> to 0.

A single write to CTICLAIMCLR can clear multiple tags to 0.

If x is greater than or equal to the IMPLEMENTATION DEFINED number of CLAIM tags, this bit is RAZ/WI.

An External Debug reset clears the CLAIM tag bits to 0.

## Accessing CTICLAIMCLR

#### CTICLAIMCLR can be accessed through the external debug interface:

Component | Offset | Instance
--- | --- | ---
CTI | 0xFA4 | CTICLAIMCLR

This interface is accessible as follows:

- When SoftwareLockStatus(), accesses to this register are RO.
- Otherwise, accesses to this register are RW.
