Parameter
ALE to RD/ = Minimum delay from ALE falling to RD/ falling
RD/ pulse width = Minimum time RD/ is low
RD/ to valid data in = Maximum delay from RD/ falling to data valid
Data hold after RD/
Data float after RD/
Address Valid to ALE Falling = Minimum setup time for A[15:8] and
AD[7:0] to ALE falling
ALE Falling to Lower Address Valid = Maximum delay from ALE
