The MSC8101ADS-ECOM set-up is preferable to the two-MSC8101ADS set-up because it allows the
MSC8101 device to handle two fast Ethernet connections over both FCC1 and FCC2 simultaneously. The
MSC8101ADS-ECOM set-up is the one that is used for the 2FCC project described in this application
note.

The ECOM can also be replaced by a second ADS with the same board interconnections.
However, a small piece of code is required for the second ADS to enable the Ethernet
transceiver and disable the local GPIO. The code can be downloaded from a PC or run directly
from the on-board Flash memory.
