Table 3-6: UART "B"/ LIN "A" jumper settings

3.6 UART "C" / LIN "B"

One RS232-transceiver (U10) or one LIN-transceiver (U8) can be connected to one of the
microcontroller's UART interfaces. Connect to D-Sub X12 corresponding RS232 or LIN
cable. By default RS232 is selected to X12.
JP67 Selects if RS232 or LIN is connected to SIN6 of MCU
JP68 Selects if RS232 or LIN is connected to SOT6 of MCU
JP65 Selects if UARTC or LINB is connected to pin2 of X12
JP69 Some programs (e.g. Terminals) need a connection between CTS and RTS
JP57 Enable LIN-Transceiver
JP54 Selects LIN Master mode
JP60 Connects Vs (Pin 1 of X12) to Vin
