3.10 CAN“B”
(JP: 27, 28)
One high-speed CAN-transceiver can be connected to the microcontroller’s CAN interface.
JP27, JP28
connects a CAN-port to the CAN-transceiver (U8, X11).
If the CAN interface is not used then the jumpers should be left open.
JP33
selects power supply of the CAN B transceiver (5V / 3V3)
Jumper
Setting
Description
JP27 (CAN”A”TX)
closed
TX2 of MCU is connected to CAN”B”
JP28 (CAN”A”RX)
closed
RX2 of MCU is connected to CAN”B”
1-2
CAN B VCC is set to 5V
JP33 (VCC CAN B)
2-3
CAN B VCC is set to 3V3
3.11 I²C Pull-Up
(JP: 46, 47)
Two 10k Ohm resistors can be connected to the SDA0 and SCL0 lines.
Jumper
Setting
Description
JP46 (SDA0)
closed
SDA0 is pulled up to VCC
JP47 (SCL0)
closed
SCL0 is pulled up to VCC
3.12 C-Pin Capacitor
For normal operation the C-pin must be connected to two capacitors. For test purposes you
can disconnect these two capacitors.
Jumper
Setting
Description
closed
C-Pin is connected to capacitors for normal
operation
JP40 (C-Pin)
open
C-Pin is left open (not recommended for normal
operation)
