USART SYNCHRONOUS SLAVE
RECEPTION
The operation of the Synchronous Master and Mlave
modes is identical except in the case of the Sleep
mode. Also, 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 bit 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).
Follow these steps when setting up a Synchronous
Slave Reception:
1.
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.
2.
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
complete 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
bit CREN.
