Data Sheet
6.2 Device ID and Common Flash Interface (ID-CFI) ASO Map
The Device ID portion of the ASO (word locations 0h to 0Fh) provides manufacturer ID, device ID, Sector
Protection State, and basic feature set information for the device.
ID-CFI Location 02h displays sector protection status for the sector selected by the sector address (SA) used
in the ID-CFI enter command. To read the protection status of more than one sector it is necessary to exit the
ID ASO and enter the ID ASO using the new SA. The access time to read location 02h is always t
ACC
and a
read of this location requires CE# to go High before the read and return Low to initiate the read
(asynchronous read access). Page mode read between location 02h and other ID locations is not supported.
Page mode read between ID locations other than 02h is supported.
For additional information see ID-CFI ASO on page 35.

and then enter ID-CFI ASO again with the new SA.
