TABLE 10-8:
REGISTERS ASSOCIATED WITH SYNCHRONOUS MASTER RECEPTION
10.4
USART Synchronous Slave Mode
Synchronous Slave mode differs from the Master
mode, in that the shift clock is supplied externally at the
RC6/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>).
10.4.1
USART SYNCHRONOUS SLAVE
TRANSMIT
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)
The first word will immediately transfer to the
TSR register and transmit when the master
device drives the CK line.
b)
The second word will remain in TXREG register.
c)
Flag bit TXIF will not be set.
d)
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.
e)
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).
Follow these steps when setting up a Synchronous
Slave Transmission:
1.
Enable the synchronous slave serial port by set-
ting bits SYNC and SPEN and clearing bit
CSRC.
2.
Clear bits CREN and SREN.
3.
If interrupts are desired, then set enable bit
TXIE.
4.
If 9-bit transmission is desired, then set bit TX9.
5.
Enable the transmission by setting enable bit
TXEN.
6.
If 9-bit transmission is selected, the ninth bit
should be loaded in bit TX9D.
7.
Start transmission by loading data to the TXREG
register.
8.
If using interrupts, ensure that GIE and PEIE in
the INTCON register are set.

Note
1: Bits PSPIE and PSPIF are reserved on the PIC16F73/76 devices; always maintain these bits clear.
