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., 02000h is block 2’s beginning location when the block size is
128 KB).
Offset 15 defines “P” which points to the Primary Numonyx-Specific Extended Query Table.
BA = The beginning location of a Block Address (i.e., 010000h is block 1’s (64-KW block) beginning location in word
mode).

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.
CFI Query Identification String
The CFI Query 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).
