I am attempting to use a SPI NOR flash memory IC that is said to support CFI (Common Flash Interface) and the JEDEC flash command set. This sounds great however I have been unable to find any documentation on what the JEDEC command set is specifically or how to interface with this device.

Does anybody know of a reference for this information?

The CFI Specification can be downloaded from jedec.org.
