Notes:

28.CE0 = OE = LB = UB = VIL; CE1 = R/W = CNTRST = MRST = MKLD = MKRD = VIH.

29.Address in output mode. Host must not be driving address bus after time tCKLZ in next clock cycle.

30.Address in input mode. Host can drive address bus after tCKHZ.

31.This is the value of the address counter being read out on the address lines.
