8.4.3 Reverse Polarity Mode

The TCAN4420 supports a reverse polarity configuration when the SW pin is connected to supply. In this configuration, both the driver and receiver remain fully operational, the key difference being that both V_OD and V_ID are now defined as the difference between CANL and CANH pins as indicated in Table 2. Also see Table Table 3 and Table 4 for the pin voltage levels in this configuration.
