2.2 Using the LIN-interface
The UART of the MB89210series supports the LIN-protocol. A LIN-transceiver is available
on the evaluation board. Set the jumpers shown below in order to use the LIN-interface
The jumpers LUO, LUI and LUC have to be shortcut on the daughter board, as well as the
jumpers LIN-RxD, LIN-TxD and LNP on the main board.
Do not connect the jumper LMP of the main board, because the MB89210series does not
support the master bus-mode.
Take care to enable the on board LIN-transceiver by setting the signal LUC to ‘high’ level.
The signal LUC is controlled by port P17:
DDR1_D17 = 1; // enable LIN-transceiver
PDR1_P17 = 1; // set Jumper LUC
NOTE:
LIN-interface and RS232-interface cannot be used at the same time, because the
MB89210series supports only one UART that can be directed either to the LIN- or to the
RS232-interface!
