PIC18F87J90 FAMILY
20.5.2
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
RCREG2 register; if the RC2IE enable bit is set, the
interrupt generated will wake the chip from 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, RC2IE.
If 9-bit reception is desired, set bit, RX9.
To enable reception, set enable bit, CREN.
Flag bit, RC2IF, will be set when reception is
complete. An interrupt will be generated if
enable bit, RC2IE, was set.
Read the RCSTA2 register to get the 9th bit (if
enabled) and determine if any error occurred
during reception.
Read the 8-bit received data by reading the
RCREG2 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.
