The networking block supports both CAN and LIN interface:
The CAN transceivers are embedded on the UC3C-EK (U9 and U11) and termination resistors can be used as bus configuration through 2-pin headers (J9 and J14). See Configurations and Test Points. The physical connections of CAN bus are accessible through DB9 connectors (J10 and J15).
The LIN transceivers are embedded on the UC3C-EK (U10 and U12). The master/slave configurations are accessible through 2-pin headers (J12 and J17). The board supports also the capability to be powered-up by LIN bus through 2 pin headers (J11 and J16). See Configurations and Test Points. The physical connections of LIN bus are accessible through 3-pins headers (J13 and J18).
