Quad I/O Fast Read (EBH)
The Quad I/O Fast Read command is similar to the Dual I/O Fast Read command but with the capability to input the
3-byte address (A23-
0) and a “Continuous Read Mode” byte and 4-dummy clock4-bit per clock by IO0, IO1, IO2, IO3, each
bit being latched in during the rising edge of SCLK, then the memory contents are shifted out 4-bit per clock cycle from IO0,
IO1, IO2, IO3. The command sequence is shown in followed Figure13. The first byte addressed can be at any location. The
address is automatically incremented to the next higher address after each byte of data is shifted out. The Quad Enable bit
(QE) of Status Register (S9) must be set to enable for the Quad I/O Fast read command.
