I am using NOR-flash( XCF128XFT64C ) to configure FPGA! And I want to access flash and write/read user data after configuration by VHDL .
But I don't know how to identify writing command and data for flash? Flash datasheet is DS617.pdf
I want to know flash chips how to identify command and data? Exactly, Which is the difference between writing command and writing data?
Can anyone help me?

Can anyone answer me ?
ds617 datasheet indicate flash can be Standard NOR-Flash Interface for Access to Code or
Data Storage .
But i think the difference is exist in read and write operation between xilinx nor_flash and others flash (foe instance,Inter).
Please help me!
