11.2.5
Once Synchronous mode is selected, reception is
enabled
(RCSTA<5>), or enable bit CREN (RCSTA<4>). Data is
sampled on the RC7/RX/DT pin on the falling edge of
the clock. If enable bit SREN is set, then only a single
word is received. If enable bit CREN is set, the recep-
tion is continuous until CREN is cleared. If both bits are
set, CREN takes precedence. After clocking the last bit,
the received data in the Receive Shift Register (RSR)
is transferred to the RCREG register (if it is empty).
When the transfer is complete, interrupt flag bit RCIF
(PIR1<5>) is set. The interrupt from the USART can be
enabled/disabled by setting/clearing enable bit RCIE
(PIE1<5>). Flag bit RCIF is a read only bit, which is
reset by the hardware. In this case, it is reset when the
RCREG register has been read and is empty. The
RCREG is a double buffered register, i.e., it is a
two-deep FIFO. It is possible for two bytes of data to be
received and transferred to the RCREG FIFO and a
third byte to begin shifting into the RSR register. On the
clocking of the last bit of the third byte, if the RCREG
register is still full, then overrun error bit OERR
(RCSTA<1>) is set. The word in the RSR will be lost.
The RCREG register can be read twice to retrieve the
two bytes in the FIFO. Bit OERR has to be cleared in
software (by clearing bit CREN). If bit OERR is set,
transfers from the RSR to the RCREG are inhibited,
and no further data will be received; therefore, it is
essential to clear bit OERR if it is set. The ninth receive
bit is buffered the same way as the receive data. Read-
ing the RCREG register will load bit RX9D with a new
value, therefore it is essential for the user to read the
RCSTA register before reading RCREG in order not to
lose the old RX9D information.

Initialize the SPBRG register for the appropriate

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 interrupt enable bits
RCIE (PIE1<5>), PEIE (INTCON<6>), and GIE
(INTCON<7>), as required.
If 9-bit reception is desired, then set bit RX9.
If a single reception is required, set bit SREN.
For continuous reception set bit CREN.
Interrupt 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 ninth bit (if
enabled) and determine if any error occurred
during reception.
Read the 8-bit received data by reading the
RCREG register.
