CTIITCTRL, CTI Integration mode Control register

The CTIITCTRL characteristics are:

Purpose

Enables the CTI to switch from its default mode into integration mode, where test software can control directly the inputs and outputs of the PE, for integration testing or topology detection.

Configuration

It is IMPLEMENTATION DEFINED whether CTIITCTRL is implemented in the Core power domain or in the Debug power domain.

Implementation of this register is OPTIONAL.

Attributes

CTIITCTRL is a 32-bit register.

Field descriptions

The CTIITCTRL bit assignments are:

313029282726252423222120191817161514131211109876543210
RES0IME

Bits [31:1]

Reserved, RES0.

IME, bit [0]

Integration mode enable. When IME == 1, the device reverts to an integration mode to enable integration testing or topology detection. The integration mode behavior is IMPLEMENTATION DEFINED.

IMEMeaning
0b0

Normal operation.

0b1

Integration mode enabled.

The following resets apply:

  • If the register is implemented in the Core power domain:

    • On a Cold reset, this field resets to 0.

    • On an External debug reset, the value of this field is unchanged.

    • On a Warm reset, the value of this field is unchanged.

  • If the register is implemented in the External debug power domain:

    • On a Cold reset, the value of this field is unchanged.

    • On an External debug reset, this field resets to 0.

    • On a Warm reset, the value of this field is unchanged.

Accessing the CTIITCTRL

CTIITCTRL can be accessed through the external debug interface:

ComponentOffsetInstance
CTI0xF00CTIITCTRL

This interface is accessible as follows:

  • When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus() and SoftwareLockStatus() accesses to this register are RO.
  • When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus() and !SoftwareLockStatus() accesses to this register are RW.
  • Otherwise accesses to this register are IMPDEF.
