Table 7. Block Status Register
Description
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
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.
