From section 20.2 of the data sheet
The EUSART transmits and receives the LSb first. The
EUSART’s transmitter and receiver are functionally
independent but use the same data format and baud
rate. The Baud Rate Generator produces a clock, either
x16 or x64 of the bit shift rate, depending on the BRGH
and BRG16 bits (TXSTAx<2> and BAUDCONx<3>).
Parity is not supported by the hardware but can be
implemented in software and stored as the 9th data bit.
