Note 1:
When using byte mode transfers A8–A15 are only TRI-STATE on the last transfer, waz timing is only valid for last transfer in a burst.
Note 2:
These limits include the RC delay inherent in our test method. These signals typically turn off within bch
a
15 ns, enabling other devices to drive these
lines with no contention.
