11.1.10 Quad Enable (QE)
The Quad Enable (QE) bit is a non-volatile read/write bit in the status register (S9) that allows Quad SPI
operation. When the QE bit is set to a 0 state (factory default), the /WP pin and /HOLD are enabled.
When the QE bit is set to a 1, the Quad IO2 and IO3 pins are enabled.
WARNING: The QE bit should never be set to a 1 during standard SPI or Dual SPI operation if the
/WP or /HOLD pins are tied directly to the power supply or ground.
