Initialize the SPBRGH, SPBRGL register pair
and the BRGH and BRG16 bits to achieve the
desired baud rate (see Section 27.3 “EUSART
Baud Rate Generator (BRG)”).
Clear the ANSEL bit for the RX pin (if applicable).
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 will be set when a
character is transferred from the RSR to the
receive buffer. An interrupt will be generated if
the RCIE interrupt enable bit was also set.
Read the RCSTA register to get the error flags
and, if 9-bit data reception is enabled, the ninth
data bit.

from the receive buffer by reading the RCREG
register.

Asynchronous Reception Set-up:
This timing diagram shows three words appearing on the RX input. The RCREG (receive buffer) is read after the third word,
