Once Synchronous mode is selected, reception is
enabled by setting either the Single Receive Enable bit,
SREN (RCSTAx<5>), or the Continuous Receive
Enable bit, CREN (RCSTAx<4>). Data is sampled on
the RXx 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:

Note: Timing diagram demonstrates Sync Master mode with bit SREN = 1 and bit BRGH = 0.
Initialize the SPBRGHx:SPBRGx 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.

Ensure bits CREN and SREN are clear.
If interrupts are desired, set enable bit RCxIE.
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 RCxIF will be set when
reception is complete and an interrupt will be
generated if the enable bit RCxIE was set.
