phyCORE-TriCore Development Board
1.3.6
Second CAN Interface at Plug P2B
Plug P2B is the upper plug of the double DB-9 connector at P2. P2B is
connected to the second CAN interface (CAN1) of the
phyCORE-TC1130 or phyCORE-TC1796 via jumpers. Depending on
the configuration of the CAN transceivers and their power supply, the
following three configurations are possible:
1.
CAN transceiver populating the phyCORE-TC1130 is enabled and
the CAN signals from the module extend directly to plug P2B.
