phyCORE-TriCore Development Board
3.
The CAN transceiver populating the phyCORE-TC1130 or
phyCORE-TC1796 is disabled; CAN signals generated by the
CAN transceiver (U3) on the Development Board extend to
connector P2A
with galvanic separation.
This configuration
requires connection of an external CAN supply voltage of
7 to 13 V. The external power supply must be
only
connected to
either P2A
or
P2B.
