The ITCTRL register characteristics are:
Enables topology detection. See the ARM® CoreSight™ Architecture Specification.
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 the purposes of integration testing and topology detection.
When a device is in integration mode, the intended functionality might not be available.
After performing integration or topology detection, you must reset the system to ensure correct behavior of CoreSight and other connected system components that the integration or topology detection can affect.
There are no usage constraints.
This register is available in all configurations.
See the register summary in Table 3.79.
