3.7 LIN”A”
(JP: 17, 18, 21, 22, 44)
One LIN-transceiver (U5, X8) can be connected to one of the microcontroller’s UART
interfaces.
JP17
enable LIN-Transceiver
JP18
LIN Master-mode
JP21, JP22
connects UART 7 to the LIN-transceiver (U5, X8)
If the LIN interface is not used then the jumpers should be left open.
