Query Structure Overview
The Query command causes the flash device to display the Common Flash Interface
(CFI) Query structure or database.
address locations.
Block Status Register
The Block Status Register indicates whether an erase operation completed successfully,
a given block is locked, or a given block can be accessed for flash memory program/
erase operations.
Block Erase Status (BSR.1) allows system software to determine the success of the last
block erase operation. Use BSR.1 just after power-up to verify that the VCC supply was
not accidentally removed during an erase operation.
