Virtex® Family FPGAs

Hello ：

          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?

Thanks!

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!
