The Query command causes the flash component to display the Common Flash Interface (CFI)
Query structure or database.
locations.
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.
