Query Structure Overview
The Query command causes the flash device to display the Common Flash Interface (CFI) Query
structure or database. Table 34 summarizes the structure sub-sections and address locations.
Table 34.
Query Structure
Notes:
1.
Refer to the Section B.1, “Query Structure Output” on page 93 and offset 28h, for the detailed definition
of the offset address as a function of the flash device bus width and mode.
2.
BA = Block Address beginning location (for example, 08000h is the block 1’beginning location when the
block size is 32K-word).
3.
Offset 15 defines P, which points to the Primary Intel-specific Extended Query Table.
