18.4.2
Once Synchronous mode is selected, reception is
enabled by setting either the Single Receive Enable bit,
SREN (RCSTA1<5>), or the Continuous Receive
Enable bit, CREN (RCSTA1<4>). Data is sampled on
the RX1 pin on the falling edge of the clock.
If enable bit, SREN, is set, only a single word is
received. If enable bit, CREN, is set, the reception is
continuous until CREN is cleared. If both bits are set,
then CREN takes precedence.
To set up a Synchronous Master Reception:

Name
Initialize the SPBRGH1:SPBRG1 registers for the
appropriate baud rate. Set or clear the BRG16 bit,
as required, to achieve the desired baud rate.
Enable the synchronous master serial port by
setting bits, SYNC, SPEN and CSRC.

Bit 3
Ensure bits, CREN and SREN, are clear.
If interrupts are desired, set enable bit, RC1IE.
If 9-bit reception is desired, set bit, RX9.
If a single reception is required, set bit, SREN.
For continuous reception, set bit, CREN.
Interrupt flag bit, RC1IF, will be set when
reception is complete and an interrupt will be
generated if the enable bit, RC1IE, was set.
Read the RCSTA1 register to get the 9th bit (if
enabled) and determine if any error occurred
during reception.
