Query Structure Overview
The Query command causes the flash component to display the Common Flash
Interface (CFI) Query structure or “database.” The structure sub-sections and address
locations are summarized below. See AP-646 Common Flash Interface (CFI) and
Command Sets (order number 292204) for a full description of CFI.
The following sections describe the Query structure sub-sections in detail.

“R”
Note:
1.
The system must drive the lowest order addresses to access all the device's array data when the device is configured in
x8 mode. Therefore, word addressing, where these lower addresses are not toggled by the system, is "Not Applicable"
for x8-configured devices.
