7.34. Disable QPI (FFH)
To exit the QPI mode and return to Standard/Dual/Quad SPI mode, the “Disable QPI (FFH)” command must
be issued. When the device is switched from QPI mode to SPI mode, the existing Write Enable Latch and
Program/Erase Suspend status, and the Wrap Length setting will remain unchanged.
