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) =
=5V)
(with wait, accessing external memory)
