28.1.1.3 Transmit Data Polarity
The polarity of the transmit data can be controlled with the SCKP
bit of the BAUDxCON register. The default state of this bit is ‘0
’ which selects high true transmit idle and data bits.
Setting the SCKP bit to ‘1
’ will invert the
transmit data resulting in low true idle and data bits. The SCKP bit controls transmit data
polarity in Asynchronous mode only. In Synchronous mode, the SCKP bit has a different
function. See the 28.3.1.2 Clock Polarity section for more details.
