If the Cortex®‑R8 processor has only two cores and the Split/lock infrastructure implemented, the two core cluster can operate in either split mode or locked mode.
You can select the usage mode with the SAFEMODE input signal. This input can be changed only while the two core processor is held in reset and must remain stable when out of reset.
For more information about how to make a change in your system, contact your system integrator.
If you are implementing a Split/lock configuration, contact ARM for more information.
