DEVICE OPERATION (CONTINUED)
FAST_READ COMMAND (FAST READ DATA) OPERATION
The FAST_READ instruction is used to read memory data at
up to a 100 MHz clock.
The FAST_READ instruction code is followed by three
address bytes (A23 - A0) and a dummy byte (8 clocks),
transmitted via the SI line, with each bit latched-in during the
rising edge of SCK. Then the first data byte addressed is
shifted out on the SO line, with each bit shifted out at a
maximum frequency fCT, during the falling edge of SCK.

The first byte addressed can be at any memory location. The
address is automatically incremented after each byte of data
is shifted out. When the highest address is reached, the
address counter will roll over to the 000000h address,
allowing the entire memory to be read with a single
FAST_READ instruction. The FAST_READ instruction is
terminated by driving CE# high (VIH).
