10.2.8 Fast Read (0Bh)  
The Fast Read instruction is similar to the Read Data instruction except that it can operate at the  
highest possible frequency of FR (see AC Electrical Characteristics). This is accomplished by adding  
eight “dummy” clocks after the 24-bit address as shown in figure 9. The dummy clocks allow the  
devices internal circuits additional time for setting up the initial address. During the dummy clocks the  
data value on the DIO pin is a “don’t care”.
