3.5 CAN interfaces (X7-X8)
Two high-speed CAN-transceivers can be connected to the microcontroller's CAN interfaces
(CAN0-CAN1).
Jumper
JP69 (CAN0 RX)
JP72 (CAN0 TX)
JP70 (CAN1 RX)
JP73 (CAN1 TX)
By default, twol CAN Interfaces are connected to X7-X8.
3.6 Reset Generation (JP: 13, 15, 16, 18, 29, 32, 38, 42, 43)
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 (X2 – X5)' for DTR / RTS selection.
JP15, 16, 42, 43: Selects X2, X3, X4 or X5 as reset source
The signal on the DTR/RTS line can be negated with this jumper.
JP13
Remove the jumper in order to disable the RS232 reset circuit.
This solder jumper selects between normal (immediate) reset and delayed reset.
JP18
In delayed reset mode, the reset button has to be held down for 2 sec before a
reset is generated to avoid accidental resets.
This solder jumper selects the third voltage monitored by the reset IC (5V and
JP29
3.3V are always monitored).
This solder jumper selects the third voltage monitored by the reset IC (5V and
JP32
3.3V are always monitored).
Open this jumper if no external Reset shall be generated.
JP38
In this case only the internal reset is active (e.g.: power-on)
