phyCORE-TriCore Development Board
1.3.5
First CAN Interface at Plug P2A
Plug P2A is the lower plug of the double DB-9 connector at P2. P2A
is connected to the first CAN interface (CAN0) 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 or phyCORE-
TC1796 is enabled and the CAN signals from the module extend
directly to plug P2A.
