3.11
3.11.1
If the high-speed SerDes interface is not used at all, the unused pin should be terminated as described in this section. However,
the SerDes must always have power applied to its supply pins. See SerDes1 in
The following pins must be left unconnected (float):
The following pins must be connected to XGND:
The POR configuration pin cfg_io_ports[0:2] on TSEC3_TXD[6:3] can be used to power down SerDes 1 block for power
saving. Note that both SVDD and XVDD must remain powered.
3.11.2
If only part of the high speed SerDes interface pins are used, the remaining high-speed serial I/O pins should be terminated as
described in this section.
The following pins must be left unconnected (float) if not used:
