10.4.17. Integration Mode Control Register

The DBGITCTRL characteristics are:


Switches the processor from its default functional mode into integration mode, where test software can control directly the inputs and outputs of the processor, for integration testing or topology detection. When the processor is in integration mode, the test software uses the integration registers to drive output values and to read inputs.

Usage constraints

DBGITCTRL is not accessible on the extended CP14 interface.


Available in all configurations.


See the register summary in Table 10.1.
