Table 25. Example of Query Structure Output of x16 Devices (Sheet 2 of 2)
Table 26. Query Structure
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.
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 VCC supply was not
accidentally removed during an erase operation.
