12.4
Synchronous Slave Mode differs from Master Mode in
the fact that the shift clock is supplied externally at the
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>).
12.4.1
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:
a)
b)
c)
d)
e)

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 inter-
rupt vector (0004h).
Enable the synchronous slave serial port by set-
ting 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 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.

12.4.2
The operation of the synchronous master and slave
modes is identical except in the case of the SLEEP
mode. Also, enable bit SREN is a don't care in slave
mode.
If receive is enabled by setting bit CREN 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 enable bit RCIE 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 bits SYNC and SPEN, and clearing bit
CSRC.
If interrupts are desired, then set enable bit
RCIE.
If 9-bit reception is desired, then set bit RX9.
To enable reception, set enable bit CREN.
Flag bit RCIF will be set when reception is com-
plete, 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.
If any error occurred, clear the error by clearing
enable bit CREN.
