3.8.3 UART 5
UART5 (connector X8) is selected as RS-232 at default setting.
JP79 Select, if SIN5 is connected to RS-232- or LIN-transceiver
JP81 Select, if SOT5 is connected to RS-232- or LIN-transceiver
JP84 Select, if RS-232- or LIN-transceiver is connected to X8 pin2 (shared pin)
JP78 Some terminal programs needs a connection between CTS and RTS
JP80 Selects, if DTR or RTS will be used for system reset
generation
JP85 Enables the LIN transceiver
JP86 Selects, if UART5 will be LIN master or LIN slave
