3.5 CAN interfaces (X6 and X8)

Two high-speed CAN-transceivers can be connected to the microcontroller's CAN interfaces

(CAN0 and CAN1).

Jumper

JP24 (CAN0 RX)

JP26 (CAN0 TX)

JP34 (CAN1 RX)

JP35 (CAN1 TX)

3.6 Reset Generation (JP: 32, 33, 41, 48)

In addition to the internal Power-On reset, the microcontroller can be reset by an external

reset circuit (Voltage Monitor) and also by a RS232 interface. Refer to the chapter 'LIN /

UART Connectors (X5 or X9)' for DTR / RTS selection.

JP33

Selects X5 or X9 as reset source

JP41

The signal on the DTR/RTS line can be negated with this jumper.

Remove the jumper in order to disable the RS232 reset circuit.

JP46

With this jumper the time to hold down reset button SW6 controlled

JP48

Open this jumper if no external Reset shall be generated.

In this case only the internal reset is active (e.g.: power-on)

Jumper

JP33 (UART RESET)

JP41 (DTR / DTRx)

JP46

(Reset imm./delayed)

JP48 (RST MCU)

By default, the external reset is enabled and set to immediate reset, the reset by UART is

disabled.
