PRELIMINARY
BLOCK LOCK 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 V
CC
supply was not accidentally removed
during an erase operation. This bit is only reset by issuing another erase operation to the block. The Block
Status Register is accessed from word address 02h within each block.
