Lin / Uart - Fujitsu SK-96380-120PMC User Manual

3.9 LIN / 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.
