A system includes an interface with a plurality of sub-addresses. The interface receives critical data and non-critical data. The critical data are received only at more specific sub-addresses of the interface. The interface transfers the critical data received at the sub-addresses to a critical processor, such that the critical data avoids being received by or being processed by a non-critical processor. The interface transfers the non-critical data from the interface to the non-critical processor. The configuration of the interface is hard-coded such that the configuration of the interface is fixed at power up of the interface and is non-changeable by the non-critical processor. The interface includes an external platform interface that is external to the critical processor, the non-critical processor, and a local controller. The external platform interface includes a limited ability to store the critical and non-critical data.
