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.
The access time to read location 02h is always tACC 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.
In x8 mode, address A-1 is ignored and the lower 8 bits of data will be returned for both address, in CFI only. While in x8 only CFI or
only Autoselect data can be read. In x16 mode, able to read both memories from either command.
For additional information see ID-CFI ASO on page 32.
