MII Port Operation
The LXT98x3 MII ports allow direct connection with a MAC. The MII ports can operate at either
10 Mbps or 100 Mbps. Speed control is provided via MII
n_
SPD. For 100 Mbps operation, set
MII
n
_SPD = 1. For 10 Mbps operation, set MII
n_
SPD = 0.
3.8.1
Preamble Handling
When operating at 100 Mbps, the LXT98x3 passes the full 56 bits of preamble through before
sending the SFD. When operating at 10 Mbps, the LXT98x3 sends data across the MII starting
with the 8-bit SFD (no preamble bits).
