A. All XINTF accesses (lead period) begin on the rising edge of XCLKOUT. When necessary, the device will insert an
alignment cycle before an access to meet this requirement.
B. During alignment cycles, all signals will transition to their inactive state.
C. For USEREADY = 0, the external XREADY input signal is ignored.
D. XA[0:18] will hold the last address put on the bus during inactive cycles, including alignment cycles.
