3.8.1 UART 2
UART2 (connector X1) is selected as LIN master at default setting.
J
P37 Select, if SIN2 is connected to RS-232- or LIN-transceiver
JP44 Select, if SOT2 is connected to RS-232- or LIN-transceiver
JP46 Select, if RS-232- or LIN-transceiver is connected to X1 pin2 (shared pin)
JP30 Some terminal programs needs a connection between CTS and RTS
JP39 Selects, if DTR or RTS will be used for system reset generation
JP47 Enables the LIN transceiver
JP51 Selects, if UART2 will be LIN master or LIN slave
