Honored ContributorCONF_DONE as input?
Hello, sorry if this has been asked already. Specifically for Cyclone V: so CONF_DONE is a bidirectional pin. Its function as input is not very clear or not very well documented or maybe I mis...

Honored ContributorCONF_DONE is an input when multiple FPGAs are configured sequentially; as each FPGA configures they release their CONF_DONE driver (which was driving low) and then wait for the CONF_DONE signal to go high before entering user mode. This ensures that all FPGAs enter user-mode once configuration of all devices is done.
--- Quote Start --- I'd like to be able to delay entering user mode, after configuration has finished, and I wonder if I could do that by holding CONF_DONE low --- Quote End --- Yes, this is ok, and used to be stated in some of the device handbooks. Cheers, Dave
