CTIINEN<n>, CTI Input Trigger to Output Channel Enable registers, n = 0 - 31

The CTIINEN<n> characteristics are:


Enables the signaling of an event on output channels when input trigger event n is received by the CTI.


CTIINEN<n> is in the Debug power domain.

If input trigger n is not connected, the behavior of CTIINEN<n> is IMPLEMENTATION DEFINED.


CTIINEN<n> is a 32-bit register.

Field descriptions

The CTIINEN<n> bit assignments are:

INEN<x>, bit [x]

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

Input trigger <n> to output channel <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:


Input trigger <n> will not generate an event on output channel <x>.


Input trigger <n> will generate an event on output channel <x>.

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

Accessing the CTIINEN<n>

CTIINEN<n> can be accessed through the external debug interface:

CTI0x020 + 4nCTIINEN<n>

This interface is accessible as follows:

  • When SoftwareLockStatus() accesses to this register are RO.
  • When !SoftwareLockStatus() accesses to this register are RW.
