CTIAPPSET, CTI Application Trigger Set register

The CTIAPPSET characteristics are:


Sets bits of the Application Trigger register.


CTIAPPSET is in the Debug power domain.


CTIAPPSET is a 32-bit register.

Field descriptions

The CTIAPPSET bit assignments are:

APPSET<x>, bit [x]

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

Application trigger <x> enable.

Bits [31:N] are RAZ/WI. N is the number of ECT channels implemented as defined by the CTIDEVID.NUMCHAN field.

Possible values of this bit are:


Reading this means the application trigger is inactive. Writing this has no effect.


Reading this means the application trigger is active. Writing this sets the corresponding bit in CTIAPPTRIG to 1 and generates a channel event.

If the ECT does not support multicycle channel events, use of CTIAPPSET is deprecated and the debugger must only use CTIAPPPULSE.

On a External debug reset, this field resets to an architecturally UNKNOWN value.

Accessing the CTIAPPSET

CTIAPPSET 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.
