Internal Digital Block
Figure 12 presents an overview of the functional layers of the 78Q8430. On the left side are the signals,
which connect to the GBI bus. On the upper and middle right, the blocks that implement the MAC side of
the MII are shown. These blocks are connected to the embedded PHY. On the lower right, connections
to the EEPROM are shown.

Internal PHY
Figure 13 shows the functional blocks of the internal 78Q8430 PHY. The signals shown on the left side
are the internal MII signals to the MAC. These signals are multiplexed with their respective external pins
for use with an external PHY device. The 78Q8430 is not a two-port device. Only one PHY interface can
be operational.
