and doesn't show hold time of data bus.
Hold time of data bus is different by capacitor volume and pull-up
(pull-down) resistance value.
Hold time of data bus is expressed in
by a circuit of the right figure.
For example, when V
of output “L” level is
td(DB – WR) =
RD signal output delay time
Address output hold time (BCLK standard)
Address output hold time (WR standard)
ALE signal output delay time
RD signal output hold time
WR signal output delay time
WR signal output hold time
