19.4
Synchronous Slave mode is entered by clearing bit
CSRC (TXSTAx<7>). This mode differs from the Syn-
chronous 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.
19.4.1
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 TXREGx and then the
SLEEP instruction is executed, the following will occur:
a)
b)
c)
d)
e)

Note 1:
Name
The first word will immediately transfer to the
TSR 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 TSR,
the TXREGx register will transfer the second
word to the TSR 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.
EUSART Synchronous Slave
Mode
x = unknown, – = unimplemented, read as ‘0’. Shaded cells are not used for synchronous slave transmission.
Enabled only in Microcontroller mode for PIC18F8525/8621 devices.

Bit 2
—
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.
