The device supports two polarity configurations on the CAN pins. For a conventional (normal) CAN connection, connect SW pin to GND. Allow for a time interval equal to tMODE after changing the SW pin, before reading the bus or the RXD pin. To support a reverse connection of the CAN pins, connect the SW pin to VIO. This approach enables compatibility with existing boards that already use this pin (pin 8) to be connected to GND for normal operation. See Table 2.
SW Pin | Device Polarity | VOD(TX) or VID (RX) |
---|---|---|
LOW | Normal | = CANH-CANL |
HIGH | Reverse | = CANL-CANH |
