Adding this value to the current location of 03h gives the address of the last valid location in the ID-CFI legacy address map. The legacy CFI address map ends with the Primary Vendor-Specific Extended Query. The original legacy length is maintained for backward software compatibility. However, the CFI Query Identification String also includes a pointer to the Alternate Vendor-Specific Extended Query that contains additional information related to the FS-S family. 04h 00h (Uniform 256-kB physical sectors) 01h (Uniform 64-kB physical sectors) Physical Sector Architecture The S25FS-S family may be configured with or without 4-kB parameter sectors in addition to the uniform sectors. 05h 81h (S25FS-S Family) Family ID 06h xxh ASCII characters for Model Refer to Ordering Information on page 151 for the model number definitions. 07h xxh 08h xxh Reserved 09h xxh Reserved 0Ah xxh Reserved 0Bh xxh Reserved 0Ch xxh Reserved 0Dh xxh Reserved 0Eh xxh Reserved 0Fh xxh Reserved Table 12.23 CFI Query Identification String Byte Address Data Description 10h 11h 12h 51h 52h 59h Query Unique ASCII string “QRY” 13h 14h 02h 00h Primary OEM Command Set FL-P backward compatible command set ID 15h 16h 40h 00h Address for Primary Extended Table 17h 18h 53h 46h Alternate OEM Command Set ASCII characters “FS” for SPI (F) interface, S Technology 19h 1Ah 51h 00h Address for Alternate OEM Extended Table |
