Figure 16-5. Connection of the Master Address
• For slave mode—The user has two groups of five address pins each. The user decides
which FCC uses each pin by programming CMXUAR[SADx]. Connect any UTOPIA pins
that are not connected to PowerQUICC II pins to GND. See
Figure 16-6 .

the programming. Bit 4 is the msb.
NOTE: To use FCC2 as shown, connect the FCC2 address bits reversed with
respect to the pinout address indexes. PHY address pins with no pin
connection should be connected to GND.
