Figure 4-9. RCM5700/RCM6700 Pinouts
The edge connectors are designed to interface with a 52-pin mini PCI Express socket.
Pin 8 has different functionality between the RCM5700 and RCM6700, due to differences in the
Ethernet PHY designs. On the RCM5700, it is the activity LED signal, while on the RCM6700 it
is +2.5V for the Ethernet interface.
