8.22 ENTER QUAD PERIPHERAL INTERFACE (QPI) MODE OPERATION (QPIEN,35h; QPIDI,F5h)

The Enter QPI (QPIEN) instruction, 35h, enables the Flash device for QPI bus operation. Upon completion of the

instruction, all instructions thereafter will be 4-bit multiplexed input/output until a power cycle or an Exit QPI

instruction is sent to device.

The Exit QPI instruction, F5h, resets the device to 1-bit SPI protocol operation. Prior to issuing the F5h command,

the QE bit must be set to 1. To execute an Exit QPI operation, the host drives CE# low, sends the Exit QPI command

cycle, then drives CE# high. The device just accepts QPI (2 clocks) command cycles.
