Bit 7

The operation of the synchronous master and slave modes is identical except in the case of the
SLEEP mode. Also, bit SREN is a don't care in slave mode.
If receive is enabled, by setting the CREN bit, prior to the SLEEP instruction, then a word may be
received during SLEEP. On completely receiving the word, the RSR register will transfer the data
to the RCREG register and if the RCIE enable bit bit is set, the interrupt generated will wake the
chip from SLEEP. If the global interrupt is enabled, the program will branch to the interrupt vector
(0004h).

Enable the synchronous master serial port by setting the SYNC and SPEN bits and clear-
ing the CSRC bit.
If interrupts are desired, then set the RCIE enable bit.
If 9-bit reception is desired, then set the RX9 bit.
To enable reception, set the CREN enable bit.
The RCIF bit will be set when reception is complete and an interrupt will be generated, if
the RCIE bit 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 the CREN bit.
