LIN”A”
(JP: 17, 18, 21, 22)
One LIN-transceiver is available and can be used with UART1.
JP17
enable LIN-Transceiver
JP18
LIN Master-mode
JP21, JP22
connects UART1 to the LIN-transceiver (U5, X8)
Jumper
Setting
Description
JP17 (LIN enable)
open
LIN-transceiver is disabled
closed
LIN-transceiver is enabled
JP18 (LIN Master)
open
LIN Slave-mode
closed
LIN Master-mode
JP21 (LIN”A”RXD)
open
SIN1 is disconnected from LIN-Transceiver
closed
SIN1 is connected to LIN-Transceiver
JP22 (LIN”A”TXD)
open
SOT1 is disconnected from LIN-Transceiver
closed
SOT1 is connected to LIN-Transceiver
Default: JP17, JP18, JP21, JP22 = open
By default, UART1 of MB90F387 is not used as LIN-interface.
Note: RS232- and LIN-transceiver can not be used at the same time. Take care that the
jumpers JP1 and JP2 are open if JP21 and JP22 are closed.
3.9
CAN“A”
(JP: 25, 26)
One high-speed CAN-transceiver is available on the FLASH-CAN-48P evaluation board.
JP25, JP26
connects the CAN-Port to the CAN-transceiver (U7, X10).
If the CAN interface is not used, the jumpers should be left open.
Jumper
Setting
Description
JP25 (TX0)
Open
TX is disconnected from CAN-Transceiver (U7, X10)
Closed
TX is connected to CAN-Transceiver (U7, X10)
JP26 (RX0)
Open
RX is disconnected from CAN-Transceiver (U7, X10)
Closed
RX is connected to CAN-Transceiver (U7, X10)
Default: JP25, JP26 = Closed
By default, the CAN transceiver is connected to the microcontroller
