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.
