(1) XWE1 is used in 32-bit data bus mode only. In 16-bit, this signal is XA0.
(2) During inactive cycles, the XINTF address bus always holds the last address put out on the bus. This includes alignment cycles.
(3) TW = trail period, write access (see

(1) The first XREADY (synchronous) sample occurs with respect to E in
E =(XWRLEAD + XWRACTIVE) t
c(XTIM)
When first sampled, if XREADY (synchronous) is high, then the access will complete. If XREADY (synchronous) is low, it is sampled
again each t
until it is high.
c(XTIM)
For each sample, setup time from the beginning of the access can be calculated as:
F = (XWRLEAD + XWRACTIVE +n –1) t
where n is the sample number: n = 1, 2, 3, and so forth.

E = (XWRLEAD + XWRACTIVE –2) t
c(XTIM)
XREADY (asynchronous) is low, it is sampled again each t
For each sample, setup time from the beginning of the access can be calculated as:
F = (XWRLEAD + XWRACTIVE –3 + n) t
where n is the sample number: n = 1, 2, 3, and so forth.
