Read CFI Query command
The Read Query Command is used to read data from the Common Flash Interface (CFI)
Memory Area, allowing programming equipment or applications to automatically match their
interface to the characteristics of the device. One Bus Write cycle is required to issue the
Read Query Command. Once the command is issued subsequent Bus Read operations
read from the Common Flash Interface Memory Area. See Appendix B: Common Flash
Interface (CFI), Tables 26, 27, 28, 29, 30 and 31 for details on the information contained in
the Common Flash Interface memory area.
