Hi,
I have to establish a 50MHz serial communication with a Spartan3, so:
1) should I place termination resistors on data_in, data_out or clock
pins? Value?
2) could I use somehow DCIs (I'm working with LVCMOS33 standard)?
then on the pull-up/down:
3) which JTAG pins should I pull-up? With 10KOhms?
4) I'll need to use serial mode (slave or master) also on the
configuration stage, so I could harware fix the mode pins as I'll
always be able to connect with the JTAG, no matter how the pins mode
are set, right?
Thanks,
Marco
