CTICONTROL, CTI Control register

The CTICONTROL characteristics are:


Controls whether the CTI is enabled.


CTICONTROL is in the Debug power domain. Some or all RW fields of this register have defined reset values. These apply only on an External debug reset. The register is not affected by a Warm reset and is not affected by a Cold reset.


CTICONTROL is a 32-bit register.

Field descriptions

The CTICONTROL bit assignments are:


Bits [31:1]

Reserved, RES0.

GLBEN, bit [0]

Enables or disables the CTI mapping functions. Possible values of this field are:


CTI mapping functions and application trigger disabled.


CTI mapping functions and application trigger enabled.

When GLBEN is 0, the input channel to output trigger, input trigger to output channel, and application trigger functions are disabled and do not signal new events on either output triggers or output channels. If a previously asserted output trigger has not been acknowledged, it remains asserted after the mapping functions are disabled. All output triggers are disabled by CTI reset.

If the ECT supports multicycle channel events any existing output channel events will be terminated.

On a External debug reset, this field resets to 0.

Accessing the CTICONTROL

CTICONTROL 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.
