1.2 Media Independent Interface (MII)
There are different interconnect bus formats for interfacing Ethernet controllers and transceivers, such as
MII, reduced media independent interface (RMII), and serial media independent interface (SMII). The
MSC8101 FCCs use the MII bus format. Table 2 and Table 3 show the MII device pinout for FCC2 and
FCC1. The parentheses delineate the pinout of the MSC8101ADS board.
