Uart "A" / Lin "A" (Jp: 1, 2, 9, 10, 45) - Fujitsu SK-96620_350-64PMC(1) User Manual

4.10 UART "A" / LIN "A" (JP: 1, 2, 9, 10, 45)

One LIN transceiver (LIN "A") and one RS2323 transceiver (UART "A") share one common
UART module of the microcontroller (UART2). So either the RS232 or LIN communication
can be executed at this point. In case of active LIN communication some further jumper
settings have to be done at the LIN "A" transceiver (see Table 4-11).
