TW = Trail period, write access. See Table 6-35.
A.
All XINTF accesses (lead period) begin on the rising edge of XCLKOUT. When necessary, the device inserts an
alignment cycle before an access to meet this requirement.
B.
During alignment cycles, all signals transition to their inactive state.
C.
XA[0:19] holds the last address put on the bus during inactive cycles, including alignment cycles except XA0, which
remains high.
D.
XWE1 is used in 32-bit data bus mode. In 16-bit mode, this signal is XA0.
E.
For USEREADY = 0, the external XREADY input signal is ignored.
