Enable Quad Peripheral Interface mode (EQPI) (38h)

The Enable Quad Peripheral Interface mode (EQPI) instruction will enable the flash device for Quad

SPI bus operation. Upon completion of the instruction, all instructions thereafter will be 4-bit multiplexed

input/output until a power cycle or “ Reset Quad I/O instruction “ instruction, as shown in Figure 5. The

device did not support the Read Data Bytes (READ) (03h), Dual Output Fast Read (3Bh) and Dual

Input/Output FAST_READ (BBh) modes while the Enable Quad Peripheral Interface mode (EQPI) (38h)

turns on.

Reset Quad I/O (RSTQIO) (FFh)

The Reset Quad I/O instruction resets the device to 1-bit Standard SPI operation. To execute a Reset

Quad I/O operation, the host drives CS# low, sends the Reset Quad I/O command cycle (FFh) then,

drives CS# high. This command can’t be used in Standard SPI mode.
