5.12 Reset Quad I/O (RSTQIO)

The Reset Quad I/O (RSTQIO) instruction (FFH) returns the Flash device to 1-bit SPI mode operation. To execute this operation, the host drives CE# low, sends the Reset Quad I/O command (FFH), and then drives CE# high (see Figure 5-7 for 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.
