Notes:
1. IO0 and IO1 are used for Standard and Dual SPI instructions
2. IO0 – IO3 are used for Quad SPI instructions.
3. The /RESET pin is a dedicated hardware reset pin regardless of device settings or operation states. If the hardware reset
function is not used, this pin can be left floating or connected to VCC in the system.
