If i have an external SPI FLASH connected to the FPGA and uses 'Disable Readback' in the configuration. What does it do exactly?
It is still possible to read the SPI FLASH externall?

the main feature of any ROM (including SPI Flash) is to be readable
so if you have some SPI flash then it is always possible to read back if the flash pins can be accessed by any means under software control.

To clarify further, "Disable Readback" means to disable reading the state of the FPGA from its internal SRAM. It has no effect on the configuration storage device. HTH Gabor
