Note 1
During a burst A8–A15 are not TRI-STATE if byte wide transfers are selected On the last transfer A8–A15 are TRI-STATE as shown above
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
