When the MAC function operates in half-duplex mode, these issues are observed after collisions:
- The MAC function continuously sends data out through the MII even when you do not send any data to the MAC function.No retransmit frame is available on the MAC transmit datapath when collision happens on half-duplex 10-Mbps MAC variant.The MAC function fails to copy the start-of-packet (SOP) of the subsequent frame after the retransmit frame into the retransmit buffer.
This issue affects variants of MAC function operating in half-duplex mode.
