CAN Mode versus SBC Modes
The table below indicates the CAN interface modes versus
the SBC modes as well as the status of TX, RX and the CAN
bus pins.
Table 34. CAN vs SBC Modes
How to Test the MC33989 CAN Interface
The CAN interface can be easily set up and tested.
MC33989 can be connected as in the following figure. V2 is
connected to V1. The device is supplied with nominal supply
(12 V at VSUP input pin). After power on, reset the device,
enter normal request mode, and the CAN interface is set in
normal mode, slew rate 0. TX can be driven by a signal
generator. RX will report the bus state. The figure below is a
simple test schematic.
