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. 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.
