CTIINTACK, CTI Output Trigger Acknowledge register

The CTIINTACK characteristics are:

Purpose

Can be used to deactivate the output triggers.

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

Usage constraints

This register is accessible as follows:

SLKDefault
ROWO

A debugger must read CTITRIGOUTSTATUS to confirm that the output trigger has been acknowledged before generating any event that must be ordered after the write to CTIINTACK, such as a write to CTIAPPPULSE to activate another trigger.

Configuration

CTIINTACK is in the Debug power domain.

Attributes

CTIINTACK is a 32-bit register.

Field descriptions

The CTIINTACK bit assignments are:

313029282726252423222120191817161514131211109876543210
ACK<n>, bit [n]

ACK<n>, bit [n], for n = 0 to 31

Acknowledge for output trigger <n>.

Bits [31:N] are RAZ/WI. N is the number of CTI triggers implemented as defined by the CTIDEVID.NUMTRIG field.

If any of the following is true, writes to ACK<n> are ignored:

Otherwise, if any of the following are true, it is IMPLEMENTATION DEFINED whether writes to ACK<n> are ignored:

Otherwise, the behavior on writes to ACK<n> is as follows:

ACK<n>Meaning
0

No effect

1

Deactivate the trigger.

Accessing the CTIINTACK

CTIINTACK can be accessed through the external debug interface:
