2.1 CAN
The CAN controller of the microcomputer is connected to the CAN transceiver (TJA1040). It
supports CAN physical layer. Also, CAN bus signal is connected to DSUB 9pin female
connector.
One terminal can be selected by using jumpers from maximum of three multipurpose terminals, and
can be connected to CAN transceiver.
Only one line must be shorted in each jumper.
Following table shows the connection of V850E2/PJ4.

2.2 FlexRay
The FlexRay controller of the microcomputer is externally connected to the FlexRay
transceiver (TJA1080). It supports FlexRay physical layer. Also, FlexRay bus signal is connected
to DSUB 9pin female connector.
Following table shows the connections for V850E2/PJ4.
JP11 and JP19 are jumpers for TJA1082 (not mounted). Do not short them.

EN and ERRN terminals of TJA1080 are connected as shown below logic circuit diagram.
Set EN1 terminal to Low when you need to access upper one (FlexRay A) with CSI. Set to High when
you do not need to access it.
In the same way, set EN2 terminal to Low when you need to access upper one (FlexRay B) with CSI.
Set to High when you do not need to access it.
JP5, JP7, JP17, and JP18 are the selection of FlexRay transceiver IC (TJA1080 or TJA1082).
Normally, use these with the default settings since it does not mount TJA1082.

Binary Mode 1 (SW7-1:ON, SW7-2:ON, SW7-3:Any)
It displays the hexadecimal data as sent with entering space between 1Byte data.
It can display 10Byte in 1 screen. It scrolls 1 line when it received 11Byte of data.
(example）URTH?TX = 0x01; TXWait();
URTH?TX = 0x02; TXWait();

2.6 Push Switch
4 interrupt signals can be connected to microcomputer's interrupt terminals. The signal can
be set to High by pressing H button, and to Low by pressing L button. It becomes High by reset
signal of the CPU.
Also, it has chattering prevention circuit.
The interrupt signals are disconnected by taking each jumper pin out.
