3.19 J615 CAN Bus Level Configuration
Jumper J615 is used for configuration of the CAN level power supply
on the CAN transceivers U605 and U606. In order to ensure proper
CAN_High and CAN_Low voltage levels the applicable CAN
transceiver must be supplied with the required voltage level at pin #3.
The following configurations are possible:
CAN Transceiver Supply Configuration J615
Pin 3 on CAN transceivers U605 and U606 connected
to 5 V supply voltage VDD_V5V0
(use only with TLE6250V33 devices)

Pin 3 on CAN transceivers U605 and U606 not
connected to 3.3 V supply voltage VDD_V3V3
(use only with other CAN transceivers)
