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. Only issuing
another operation to the block resets this bit. The Block Status Register is accessed
from word address 02h within each block.
CFI Query Identification String
The 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).
