desired baud rate (see
Baud Rate Generator
Set the RXx/DTx and TXx/CKx TRIS controls to
‘1’.
Enable the serial port by setting the SPEN bit
and the RXx/DTx pin TRIS bit. The SYNC bit
must be clear for asynchronous operation.
If interrupts are desired, set the RCxIE interrupt
enable bit and set the GIE/GIEH and PEIE/GIEL
bits of the INTCON register.
If 9-bit reception is desired, set the RX9 bit.
Set the DTRXP if inverted receive polarity is
desired.
Enable reception by setting the CREN bit.
The RCxIF interrupt flag bit will be set when a
character is transferred from the RSR to the
receive buffer. An interrupt will be generated if
the RCxIE interrupt enable bit was also set.
Read the RCSTAx register to get the error flags
