Refresh cycles are not executed while the bus is released, during software standby mode, and
when a bus cycle is greatly prolonged by insertion of wait states. When these conditions
occur, other means of refreshing are required.
If refresh requests occur while the bus is released, the first request is held and one refresh
cycle is executed after the bus-released state ends. Figure 7-24 shows the bus cycles in this
case.
