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], for x = 31 to 0

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.


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 an 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.
