A.3
Block Lock Status
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.
NOTE:
1.
BA = The beginning location of a Block Address (i.e., 008000h is block 1’s (64-KB block) beginning location
in word mode).
A.4
CFI Query Identification String
The CFI Query 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)
.
