QUERY STRUCTURE OVERVIEW
The QUERY command makes the Flash component
display the CFI query structure or data base. The struc-
ture subsections and address locations are outlined in
Table 6.
BLOCK STATUS REGISTER
The block status register indicates the completion
of an ERASE operation or whether a given block is locked
or can be accessed for Flash PROGRAM/ERASE opera-
tions. Block erase status (BSR1) allows system software
to recognize the success of the last BLOCK ERASE op-
eration. After power-up, BSR1 can be used just to verify
that the V
CC
supply was not accidentally removed dur-
ing an ERASE operation. By issuing another ERASE
operation to the block, this bit can be reset. Within each
block, the block status register is accessed from word
address 02h.

NOTE:
1. 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.
2. BA = Block address beginning location (i.e., 020000h is block two’s beginning location when the block size is 64K-word).
3. Offset 15 defines “ P,” which points to the Primary Extended Query Table.
