Offset
Refer to the Query Structure Output section and offset 0x28 for the detailed definition of offset address as a function of
device bus width and mode.
BA = Block Address beginning location (i.e., 0x08000 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.”
sections and address locations.
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. See
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.
