12.5
Synchronous Slave mode differs from the Master mode
in the fact that the shift clock is supplied externally at
the RB2/TX/CK pin (instead of being supplied internally
in Master mode). This allows the device to transfer or
receive data while in Sleep mode. Slave mode is
entered by clearing bit CSRC (TXSTA<7>).
12.5.1
The operation of the synchronous Master and Slave
modes are identical except in the case of the Sleep
mode.
If two words are written to the TXREG and then the
SLEEP instruction is executed, the following will occur:

BIT SREN
The first word will immediately transfer to the
TSR register and transmit.
The second word will remain in TXREG register.
Flag bit TXIF will not be set.
When the first word has been shifted out of TSR,
the TXREG register will transfer the second
word to the TSR and flag bit TXIF will now be
set.
If enable bit TXIE is set, the interrupt will wake
the chip from Sleep and if the global interrupt is
enabled, the program will branch to the interrupt
vector (0004h).

TRISB<1> bit needs to be set and TRISB<2> bit
cleared in order to configure pins RB2/TX/CK
and RB1/RX/DT as the Universal Synchronous
Asynchronous Receiver Transmitter pins.
Enable the synchronous slave serial port by
setting bits SYNC and SPEN and clearing bit
CSRC.
Clear bits CREN and SREN.
If interrupts are desired, then set enable bit
TXIE.
If 9-bit transmission is desired, then set bit TX9.
Enable the transmission by setting enable bit
TXEN.
If 9-bit transmission is selected, the ninth bit
should be loaded in bit TX9D.
Start transmission by loading data to the TXREG
register.
