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 32K-word).
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.” The structure sub-sections and address
locations are summarized below.
Block Status Register
The Block Status Register indicates whether an erase operation completed successfully
or whether a given block is locked or can be accessed for flash program/erase
operations.
Block Erase Status (BSR.1) allows system software to determine the success of the last
block erase operation. BSR.1 can be used just after power-up to verify that the VCC
supply was not accidentally removed during an erase operation.
