Query Structure Overview
The Query command causes the flash component to display the Common Flash Interface (CFI)
Query structure or “database.” The structure sub-sections and address locations are summarized
below.
Table 36.
Query Structure
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., 08000h is block 1’s beginning location when the block size
is 32K-word).
3.
Offset 15 defines “P” which points to the Primary Intel-specific Extended Query Table.
B.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.
