5.15 Reset Quad I/O (RSTQIO)

The Reset Quad I/O (RSTQIO) instruction (FFH) returns the Flash device from QPI mode to standard 1-bit SPI mode operation. To execute this operation, the host drives CE# low, transmits the Reset Quad I/O command (FFH), and then drives CE# high. Figure 5-9 illustrates the RSTQIO command sequence. When the device transitions back to SPI mode, the current Write Enable and Program/Erase Suspend status, and Wrap Length settings remain unchanged.
