3.8 LIN"B" (JP: 9, 10, 38, 39, 45)

One LIN-transceiver (U4, X6) can be connected to one of the microcontroller's UART

interfaces.

JP9

enable LIN-Transceiver

JP10

LIN Master-mode

JP38, JP39 connects UART 1 to the LIN-transceiver (U4, X6)

If the LIN interface is not used then the jumpers should be left open.

Jumper

JP9 (LIN enable)

JP10 (LIN Master)

JP38 (LIN"B"RXD)

JP39 (LIN"B"TXD)

JP45

(VBAT_B)

JP42 (WAKE)

By default, the LIN"B"-interface is not connected to a UART.

3.9 CAN"A" (JP: 19, 25, 26)

One high-speed CAN-transceiver can be connected to the microcontroller's CAN interface.

JP25, JP26 connects a CAN-port to the CAN-transceiver (U7, X10).

If the CAN interface is not used then the jumpers should be left open.

JP19

selects the power supply of the CAN A transceiver (5V / 3V3)

Jumper

JP25 (CAN"A"TX)

JP26 (CAN"A"RX)

JP19 (VCC CAN A)
