Initialize the SPBRG register and the BRGH bit
to achieve the desired baud rate (refer to
Section 16.2 “AUSART Baud Rate Generator
(BRG)”).
Enable the serial port by setting the SPEN bit.
The SYNC bit must be clear for asynchronous
operation.
If interrupts are desired, set the RCIE bit of the
PIE1 register and the GIE and PEIE bits of the
INTCON register.
If 9-bit reception is desired, set the RX9 bit.
Enable reception by setting the CREN bit.
The RCIF interrupt flag bit of the PIR1 register
will be set when a character is transferred from
the RSR to the receive buffer. An interrupt will be
generated if the RCIE bit of the PIE1 register
was also set.
Read the RCSTA register to get the error flags
and, if 9-bit data reception is enabled, the ninth
data bit.
Get the received 8 Least Significant data bits
from the receive buffer by reading the RCREG
register.
If an overrun occurred, clear the OERR flag by
clearing the CREN receiver enable bit.
