Motorola MPC8260 PowerQUICC II User Manual page 499

These 5 address bits relate to the
slave of FCC1 or FCC2 according to
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.
Figure 15-6. Connection of the Slave Address
Note that the user must program the addresses of the PHYs to be consecutive for each FCC;
that is, the address lines connected to each FCC must be consecutive.
Figure 15-7 describes the interconnection between the receive external multi-PHY bus and
the internal FCC1 and FCC2 receive multi-PHY addresses. The same diagram applies to
the transmit multi-PHY bus using different dedicated parallel I/O pins.
