Break Character Reception
The receiver is always looking for a Break sequence and can detect one,
         even in the middle of a byte reception. A Break reception is indicated by the RXBKIF flag
         (UxSTAT[2]). An interrupt can be optionally generated by setting the RXBKIE bit
         (UxSTAT[10]). The Break detection criteria can be configured using the RXBIMD bit
         (UxCON[11]). By default, the RXBKIF flag will set when the line makes a low-to-high
         transition after 11 low bit times, signaling the end of the Break sequence. Alternatively,
         when RXBIMD = 1, the flag will set when the eleventh low bit time is
         detected.
