Can Interfaces (X7+X10); Reset Generation (Jp: 50, 51, 52, 53, 60, 70, 80, 90) - Fujitsu MB91460 SERIES User Manual

3.5 CAN interfaces (X7+X10)

Two high-speed CAN-transceivers can be connected to the microcontroller's CAN interfaces
(CAN0-CAN1.
Jumper
JP34CAN0 RX)
JP35CAN0 TX)
JP37CAN1 RX)
JP38CAN1 TX)
By default, all two CAN Interfaces are connected to X7 and X10.

3.6 Reset Generation (JP: 50, 51, 52, 53, 60, 70, 80, 90)

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.
JP60, 70, 80, 90: Selects X4, X3, X5 or X2 as reset source
JP51 The signal on the DTR/RTS line can be negated with this jumper.
Remove the jumper in order to disable the RS232 reset circuit.
JP52 This solder jumper selects between normal (immediate) reset and delayed reset.
In delayed reset mode, the reset button has to be held down for 2 sec before a
reset is generated to avoid accidental resets.
JP53 Open this jumper if no external Reset shall be generated.
In this case only the internal reset is active (e.g.: power-on)
JP50 This solder jumper selects the third voltage monitored by the reset IC (1.8V and
2.5V are always monitored).
