18.4.2
The operation of the Synchronous Master and Slave
modes is identical, except in the case of the Sleep
mode and bit SREN, which 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 reg-
ister will transfer the data to the RCREG register and if
enable bit RCxIE 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.

x = unknown, – = unimplemented, read as ‘0’. Shaded cells are not used for synchronous slave reception.
Register names generically refer to both of the identically named registers for the two USART modules, where ‘x’
indicates the particular module. Bit names and Reset values are identical between modules.

Bit 2
Enable the synchronous master serial port by
setting bits SYNC and SPEN and clearing bit
CSRC.
If interrupts are desired, set enable bit RCxIE.
If 9-bit reception is desired, set bit RX9.
To enable reception, set enable bit CREN.
Flag bit RCxIF will be set when reception is
complete. An interrupt will be generated if
enable bit RCxIE was set.
Read the RCSTAx 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
RCREGx register.
If any error occurred, clear the error by clearing
bit CREN.
If using interrupts, ensure that the GIE and PEIE
bits in the INTCON register (INTCON<7:6>) are
set.
