9.2.16 Fast Read Parameter Page (5Bh)
The Fast Read Parameter Page instruction is basically the same as the Read Parameter Page
instruction except that it allows for a faster clock rate to be used. The Fast Read Parameter Page
instruction can opperate at clock rates from D.C. to a maximum of FR (see AC Electrical
Characteristics). This is accomplished by adding a “dummy” byte after the 24-bit address, as shown in
figure 19. 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”.
