2.8.2 SER1, SER2 and SER3 Ports

The three serial ports, based on the SCC2, SCC3 and SCC4 lines of the 68EN360, are configured by de-
fault as RS232 ports. They support full modem handshake and can be re-configured by other piggybacks
in the SC product line. These ports are usually used for communication between systems or to subsy-
stems/modems.
In addition, the signals of SCC2, SCC3 and SCC4 are routed to the CXC. This is mainly useful for phy-
sical adaptions where the application requirements cannot be met using SC piggybacks.
