PIC18F8722 FAMILY
20.4
Synchronous Slave mode is entered by clearing bit,
CSRC (TXSTAx<7>). This mode differs from the
Synchronous Master mode in that the shift clock is
supplied externally at the CKx pin (instead of being
supplied internally in Master mode). This allows the
device to transfer or receive data while in any low-power
mode.
20.4.1
The operation of the Synchronous Master and Slave
modes is identical, except in the case of Sleep mode.
If two words are written to the TXREGx and then the
SLEEP instruction is executed, the following will occur:
a)
b)
c)
d)
e)

Legend: — = unimplemented, read as ‘0’. Shaded cells are not used for synchronous slave transmission.
Name
The first word will immediately transfer to the
TSRx register and transmit.
The second word will remain in the TXREGx
register.
Flag bit, TXxIF, will not be set.
When the first word has been shifted out of
TSRx, the TXREGx register will transfer the
second word to the TSRx and flag bit, TXxIF, will
now be set.
If enable bit TXxIE is set, the interrupt will wake
the chip from Sleep. If the global interrupt is
enabled, the program will branch to the interrupt
vector.

Bit 3
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, set enable bit TXxIE.
If 9-bit transmission is desired, 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
TXREGx register.
If using interrupts, ensure that the GIE and PEIE
bits in the INTCON register (INTCON<7:6>) are
set.
