Refer to the CFI Structure Output section and offset 28h for the detailed definition of offset address as a function of device
bus width and mode.
BA = Block Address beginning location (i.e., 08000h is block 1’s beginning location when the block size is 32-KWord).
Offset 15 defines “P” which points to the Primary Numonyx-specific Extended CFI Table.

CFI Structure Overview
The CFI command causes the flash component to display the Common Flash Interface
(CFI) CFI structure or “database.” The structure sub-sections and address locations are
summarized below.
Offset
Read CFI Identification String
The 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).
