Initialize the SPBRG register for the appropriate baud rate. If a high speed baud rate is
desired, set bit BRGH. (Subsection
Enable the asynchronous serial port by clearing the SYNC bit, and setting the SPEN bit.
If interrupts are desired, then set the RCIE, GIE and PEIE bits.
If 9-bit reception is desired, then set the RX9 bit.
Enable the reception by setting the CREN bit.
The RCIF flag bit will be set when reception is complete and an interrupt will be generated
if the RCIE bit was set.
Read the RCSTA register to get the ninth bit (if enabled) and determine if any error
occurred during reception.
Read the 8-bit received data by reading the RCREG register.
If any error occurred, clear the error by clearing the CREN bit.
