PRELIMINARY
BLOCK STATUS REGISTER
The block status register indicates the completion of
an ERASE operation, or whether a given block is either
locked or can be accessed for PROGRAM or ERASE
operations. Block erase status (BSR1) allows system
software to recognize the success of the last BLOCK
ERASE operation. After power-up, BSR1 can be used to
verify that the V
CC
supply was not accidentally removed
during 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.
CFI QUERY IDENTIFICATION STRING
The identification string verifies whether the device
supports the CFI specification. Additionally, it indi-
cates the specification version and vendor-specified
command set(s) to be supported.
