CTICONTROL, CTI Control register

The CTICONTROL characteristics are:

Purpose

Controls whether the CTI is enabled.

Configuration

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.

Attributes

CTICONTROL is a 32-bit register.

Field descriptions

The CTICONTROL bit assignments are:

313029282726252423222120191817161514131211109876543210
0000000000000000000000000000000GLBEN

Bits [31:1]

Reserved, RES0.

GLBEN, bit [0]

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

GLBENMeaning
0b0

CTI mapping functions and application trigger disabled.

0b1

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:

ComponentOffsetInstance
CTI0x000CTICONTROL

This interface is accessible as follows:

  • When SoftwareLockStatus() access to this register is RO.
  • When !SoftwareLockStatus() access to this register is RW.
