[Note]
TRDH : Time to the point where D0-D7 pins become high impedance.
TADH, TRDH : Defined with respect to the point where the rise of /CS or /RD, whichever earlier, has reached 0.7*Vdd.
TADS : Defined with respect to the point where the rise of /CS or /RD, whichever earlier, has reached 0.2*Vdd.
TACC : Defined with respect to the point where any of /CS , /RD and A0 has changed later.
