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) or Release Quad I/O Fast Read Enhancement Mode (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.  
User also can use the 0xFFh command to release the Quad I/O Fast Read Enhancement Mode. The detail  
description, please see the Quad I/O Fast Read Enhancement Mode section.  
Note:  
If the system is in the Quad I/O Fast Read Enhance Mode under EQPI Mode, it is necessary to execute  
0xFFh command by two times. The first 0xFFh command is to release Quad I/O Fast Read Enhance Mode,  
and the second 0xFFh command is to release EQPI Mode.  
This Data Sheet may be revised by subsequent versions  
or modifications due to changes in technical specifications.
