4.12 LIN "B" (X6, JP: 9, 10, 38, 39, 45)
One LIN transceiver (LIN "B") can be connected to the microcontroller‟s sub module UART8.
Concerning pin assignment on the DSUB-9 connector see chapter 5.4.

Note:
There is no connection between MB90350 series and LIN "B"
UART8_R means a relocation of the UART8 to other port pins. Additionally to the
usual port pin configurations the relocated UART pins have to be activated in the
peripheral resource relocation register 8 (PRRR8).
