3.9LIN / UART

There are two identical circuit blocks for LIN or RS232 connections. Each of the two D-Sub connectors can be configured as LIN or RS232 interface. DTS or RTS can be selected as reset source, and RTS and CTS can be connected by a jumper, since some terminals and Flash programming tools need this connection. Pin 1 (Vs) of X5 and X9 can be connected to the voltage input of the board by jumpers in order to supply the LIN bus.

3.9.1 LIN-UART 0 (JP: 19, 21, 23, 25, 27, 28, 29, 31)

Jumper		Setting		Description
