For most of the system elements, RAM is accessed directly by the MBIST hardware and it keeps the functional RAM interfaces in their reset state while the RAM is accessed. For a few system elements, including the APU core processors, the RAM is accessed by the MBIST hardware through the RAM's functional paths used by system software. In these cases, the functional units must be operational (clocked and not held in reset).
