If a refresh request * and external bus release request occur simultaneously, the order of priority is
as follows:
As a refresh * and an external access by an internal bus master can be executed simultaneously,
there is no relative order of priority for these two operations.
Note: * The DRAM interface is not supported in the H8S/2321.
