Can I clarify please,
Do you mean the fpga as slave or master ?
if its mater, it will try to read the flash at start up,
if slave the fpga will wait to be written to,

I mean FPGA in Master SPI mode, so I understand it will start configuration after power-on or when PROGRAM_B is driven low. So it seems that my connection needs 6 lines: MOSI, DIN, CCLK , CSO_B, DONE and PROGRAM_B. I'm not sure about INIT_B.
I understand there is no Slave SPI mode.

You have this ?
page 18 shows the slave modes, the slave serial is often used to program the fpga from a MCU,
