18.2.2
The receiver block diagram is shown in Figure 18-6.
The data is received on the RX 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
in RS-232 systems.

Initialize the SPBRGH:SPBRG 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, RCIE.
If 9-bit reception is desired, set bit, RX9.
Enable the reception by setting bit, CREN.
Flag bit, RCIF, will be set when reception is
complete and an interrupt will be generated if
enable bit, RCIE, was set.
Read the RCSTA 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
RCREG register.
If any error occurred, clear the error by clearing
enable bit, CREN.

select the desired priority level with the RCIP bit.
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 RCIF bit will be set when reception is
complete. The interrupt will be Acknowledged if

Read the RCSTA register to determine if any
error occurred during reception, as well as read
