NOTES:
1. Refer to the Query Structure Output section and offset 28h for the detailed definition of offset address as a
function of device bus width and mode.
2.
BA = Block Address beginning location (i.e., 02000h is block 2’s beginning location when the block size is
128 Kbyte).
3. Offset 15 defines “P” which points to the
Primary Intel-Specific Extended Query
Table.
4.2.3
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 V
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).
4.2.4
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).
