Fast Read Dual Input-Output (BBh)
The Fast Read Dual Input-Output (BBh) instruction is similar
to the Fast_Read (0Bh) instruction except the data is input
and output on two pins, DO and DIO, instead of just DO. This
allows
A25L020/A25L010/A25L512 at twice the rate of standard SPI
devices.
Similar to the Fast Read instruction, the Fast Read Dual
Output instruction can operate at the highest possible

accomplished by adding four “dummy” clocks after the 24-bit
address as shown in figure 11. The dummy clocks allow the
device’s internal circuits additional time for setting up the
initial address. The input data during the dummy clocks is
“don’t care”. However, the DIO and DO pins should be
high-impedance prior to the falling edge of the first data out
clock.
