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”.
