The receiver block diagram is shown in Figure 19-6.
The data is received on the RX1 pin and drives the data
recovery block. The data recovery block is actually a
high-speed shifter, operating at x16 times the baud
rate, whereas the main receive serial shifter operates
at the bit rate or at F
used in RS-232 systems.

Initialize the SPBRGH1:SPBRG1 registers for
the appropriate baud rate. Set or clear the
BRGH and BRG16 bits, as required, to achieve
the desired baud rate.
Enable the asynchronous serial port by clearing
bit, SYNC, and setting bit, SPEN.
If interrupts are desired, set enable bit, RC1IE.
If 9-bit reception is desired, set bit, RX9.
Enable the reception by setting bit, CREN.
Flag bit, RC1IF, will be set when reception is
complete and an interrupt will be generated if
enable bit, RC1IE, was set.
Read the RCSTA1 register to get the 9th bit (if
enabled) and determine if any error occurred
during reception.
Read the 8-bit received data by reading the
RCREG1 register.
If any error occurred, clear the error by clearing
enable bit, CREN.

select the desired priority level with the RC1IP

Set the RX9 bit to enable 9-bit reception.
Set the ADDEN bit to enable address detect.
Enable reception by setting the CREN bit.
The RC1IF bit will be set when reception is
complete. The interrupt will be Acknowledged if
the RC1IE and GIE bits are set.
Read the RCSTA1 register to determine if any
error occurred during reception, as well as read
bit 9 of data (if applicable).
