Page 77 request has the highest priority of all requests for memory. The duration of refresh is programmable. In order to achieve zero wait state timing under a variety of system speeds, there are two sets of CAS timing control logic (16 and 25MHz). One wait state is required for DRAM writes at 25MHz. All reads at any system speed and writes below 25MHz can operate at 0 wait states, assuming the 64 bit (odd/even, MDO[31:0] and MDE[31:0]) double banking path is chosen.
