Notes:
1. IO0 and IO1 are used for Standard and Dual SPI instructions
2. IO0 – IO3 are used for Quad SPI instructions, /WP & /HOLD (or /RESET) functions are only available for Standard/Dual SPI.
3. The /RESET pin on SOIC-16 package is independent of the HOLD/RST bit and QE bit settings in the Status Register. This pin
can be treated as ‘No Connect’ in the system if RESET function is not needed
