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 F
(see AC Electrical Characteristics). This is accomplished by adding
R
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”.
