Figure 5-115 is an example of setting 16-bit data width. In this example, AD bus is used for being
address[15:0] and data[15:0]. When ALE assert to high, AD is address output. After address is
latched, ALE asserts to low and the AD bus change to high impedance to wait device output data
in read access operation, or it is used for being write data output.
