Serial Communication Controllers (SCCs)
The following pins take on new meanings when the Ethernet protocol is selected for the
SCC:
The EEST has similar names for its connection to the seven basic QUICC pins. In addition,
the EEST contains a loopback pin to allow the QUICC to perform external loopback testing.
This can be controlled by any available parallel I/O pin on the QUICC.

The carrier sense signal is often referred to in Ethernet descrip-
tions, because it defines whether the LAN is currently in use.
Carrier sense is defined as RENA ORed with CLSN.
