FCBaseAddress
Source port base address for flow control packets
FCBaseAddress
Contains a 48-bit MAC address used to generate the individual port address used in
direct flow control addressing. The port addresses are obtained by incrementing
this base address and assigning the result to the TC9208M’s ports starting with port
0. The least significant 5 bits of this address will be ignored and replaced with ‘0’, so
these bits will encode the port number in the actual port address.

TrunkA
Setting this bit to ‘1’ will enable the trunk channel A, otherwise the trunk channel A
will be disabled. Default value is its corresponding TrunkA pin value.
TrunkMode
These bits will set the balancing method for loading the two ports within the same
trunk channel. When a method is selected, both trunk channels will follow it if they
are enabled. The balancing methods cannot be set individually for the two
channels. The TrunkMode configuration pins are in effect when the EEPROM is not
present.
