15.4.2
The operation of the Synchronous Master and Slave
modes is identical, except in the case of Sleep or any
Idle mode and bit, SREN, which is a “don’t care” in
Slave mode.
If receive is enabled by setting the CREN bit prior to
entering Sleep or any Idle mode, then a word may be
received while in this low-power mode. Once the word
is received, the RSR register will transfer the data to the
RCREG register. If the RCIE enable bit is set, the
interrupt generated will wake the chip from the low-
power mode. If the global interrupt is enabled, the
program will branch to the interrupt vector.

Enable the synchronous master serial port by
setting bits, SYNC and SPEN, and clearing bit,
CSRC.
If interrupts are desired, set enable bit, RCIE.
If 9-bit reception is desired, set bit, RX9.
To enable reception, set enable bit, CREN.
Flag bit RCIF will be set when reception is
complete. An interrupt will be generated if
enable bit, RCIE, was set.
Read the RCSTA register to get the ninth 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
bit, CREN.
If using interrupts, ensure that the GIE and PEIE
bits in the INTCON register (INTCON<7:6>) are
set.
