CFI Query
The CFI Query command instructs the device to output Common Flash Interface (CFI) data when
partition addresses are read. See
Section 9.2, “Device Commands” on page 47
for details on
issuing the CFI Query command.
Appendix C, “Common Flash Interface” on page 93
shows CFI
information and address offsets within the CFI database.
Issuing the CFI Query command to a partition that is programming or erasing places that partition’s
outputs in the CFI Query state, while the partition continues to program or erase in the background.
The CFI Query command is subject to read restrictions dependent on parameter partition
availability, as described in
Table 15
.
