15 0 Switching Characteristics
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
lines with no contention
