Hi,

I am interested to know the difference between the following.


• Extended SPI (standard SPI protocol upgraded with dual and quad operations)
• Dual I/O SPI
• Quad I/O SPI
 

The difference is the number of data in parallels. I mean the basic SPI, is bit by bit, the dual SPI, is two bits by two bits...
