FXSD4

(IP175CH only)

100Base-FX Signal detect

Port 4 of IP175C can be configured to TP or FX. If FXSD4 is

connected to SD of a fiber MAU, port 4 is a fiber port. If FXSD4

is tied to GND, the port 4 is a TP port.

If port 4 is defined to be a fiber port, its speed is forced to be

100M and its duplex is defined in its MII register 4.0.8. Please

refer section 2.19 on page 56 for more detail description.
