Refer to the Query Structure Output section and offset 28h for the detailed definition of offset address as a function of
device bus width and mode.
BA = Block Address beginning location (i.e., 08000h is block 1’s beginning location when the block size is 32-KWord).
Offset 15 defines “P” which points to the Primary Numonyx-specific Extended Query Table.

Query Structure Overview
The Query command causes the flash component to display the Common Flash
Interface (CFI) Query structure or database.
sections and address locations.
CFI Query Identification String
The Identification String provides verification that the component supports the
Common Flash Interface specification. It also indicates the specification version and
supported vendor-specified command set(s).
