24.1.1.3 Transmit Data Polarity
The polarity of the transmit data can be controlled with the
Clock/Transmit Polarity Select (SCKP) bit. 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 “Clock Polarity”
section for more details.
