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 these bits to 0.

This register is part of the Cross-Trigger Interface registers functional group.

Usage constraints

This register is accessible as follows:

SLKDefault
RORW

Configuration

CTICLAIMCLR is in the Debug power domain.

See the CLAIM field description for the effect of an External debug reset on the value returned by this register. This register is not affected by a Warm reset, and is not affected by a Cold reset.

Implementation of this register is OPTIONAL.

Attributes

CTICLAIMCLR is a 32-bit register.

Field descriptions

The CTICLAIMCLR bit assignments are:

313029282726252423222120191817161514131211109876543210
CLAIM[x], bit [x]

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

CLAIM tag clear 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, reads return the value of CLAIM[x] and the behavior on writes is:

CLAIM[x]Meaning
0

No action.

1

Indirectly clear CLAIM[x] to 0.

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

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

Accessing the CTICLAIMCLR

CTICLAIMCLR can be accessed through the external debug interface:
