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 a
R
“dummy” byte after the 24-bit address as shown in figure 9. The dummy byte allows the devices
internal circuits additional time for setting up the initial address. The dummy byte data value on the DI
pin is a “don’t care”.
