34.2.1.3 Transmit Data Polarity

The polarity of the transmit data is controlled with the TXPOL bit. The default state of this bit is ‘0’, which selects high true transmit Idle and data bits. Setting the TXPOL bit to ‘1’ will invert the transmit data, resulting in low true Idle and data bits. The TXPOL bit controls transmit data polarity in all modes.
