Hi,

What is unused pin requirement for XFI pins, especially, XFIMDIO and XFITRXP ?

I found related post but it did not help. Could you clarify this ?

Best Regards,

Naoki,

If you are not using XFI interface, the peripheral should be disabled in the MMR and the XFI pins can be left floating. The XFI input clock needs termination as mentioned in the KS2 hardware design guide.
