3.3.15. Integration Mode Control Register

The STMITCTRL Register characteristics are:

Purpose

Used to enable topology detection. This register enables the component to switch from a functional mode, the default behavior, to integration mode where the inputs and outputs of the component can be directly controlled for integration testing and topology solving.

Note

When a device has been in integration mode, it might not function with the original behavior. After performing integration or topology detection, you must reset the system to ensure correct behavior of CoreSight and other connected system components that are affected by the integration or topology detection.

Usage constraints

There are no usage constraints.

Configurations

This register is available in all configurations.

Reserved.

[0]Integration_mode

Enables the component to switch from functional mode to integration mode and back. If no integration functionality is implemented, this register must read as zero.
