Transmitting a Break Character

A Break character is transmitted by setting the SENDB bit (UxCON[8]) and then writing any value to UxTXB. The contents of UxTXB will follow the Break character.

Alternatively, the BRKOVR bit (UxCON[9]) can be controlled by software to override and drive the UxTX line for any duration. When TXPOL (UxCON[18]) = 0, the UxTX line will be driven low, and when TXPOL = 1, the UxTX line will be driven high.
