I am using the Fast Ethernet Controller (FEC) on the 8260.
The FEC FPSMR[FDE] bit controls full duplex mode.
The management lines (MDC and MDIO) to the phy are not connected.
Question is can FDE be enabled for phy connections that are half duplex ?
I would like to enable FDE (Full Duplex) and be certain that this will work for both duplex connections.
The question is more about what the FCC/CPM does with collisions in full duplex mode.
I believe I found the answer in the user manual where it states that collisions are ignored in full duplex mode. It seems that to work properly, the FCC duplex mode must be set according to the established link mode.
