Port4 external MII enable
1: IP175 works as a 4-TP + 1 MII port switch
MII interface is enabled and is connected to external MAC
device. The MAC data is fed to port4 MII interface of switch
core directly and bypass the internal port4 transceiver
0: IP175 works as a 5-TP port switch
If external MII is enabled, IP175 generates MCOL to external
MAC device when both MRXDV and MTXEN are active and
P4EXT_FULL is set to logic low.
Port4 external MII interface speed selection
1: 10M
0: 100M (default)
It is valid only if P4EXT is set to logic high.
Port4 external MII interface full/half duplex selection
0: half (default)
1: full
It is valid only if P4EXT is set to logic high.
MII_FC_EN, Flow control enable for MII port
1: enable,
0: disable (default)
UTPdet
It is a power saving mode for TP port. TP port will be power
down when the cable is unplugged and the function is enabled.
