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

The Enter Quad Peripheral Interface (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 Quad Peripheral Interface instruction is sent to device.

The Exit Quad Peripheral Interface (QPIDI) instruction, F5h, resets the device to 1-bit SPI protocol operation. To

execute an Exit Quad Peripheral Interface operation, the host drives CE# low, sends the QPIDI instruction, then

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