    Words are precious today: Yes, everything is in the EPCS datasheet.

    sorry, but i read this datasheet but i don't find the answer. Maybe it's because i don't understand english very well.

    EPCS is simply an industry standard serial flash. So you can refer to the datsheets of ST/Numonyx/Micron M25P16 and similar. They are more verbose and possibly clearer in some points. There are special traps like opposite bit order for memory commands and configuration data. So don't worry, if you don't succeed at first attempt.

    You can also refer to the Altera SRUNNER project, an embedded EPCS programmer.
