Refresh Cycle Priority Order: When there are simultaneous bus requests, the priority order is:
For details see section 6.3.7, Bus Arbiter Operation.
Wait State Insertion: When bit AST3 is set to 1 in ASTCR, bus controller settings can cause wait
states to be inserted into bus cycles and refresh cycles. For details see section 6.3.5, Wait Modes.
