16.4
The AUSART will remain active during Sleep only in the
Synchronous Slave mode. All other modes require the
system clock and therefore can not generate the
necessary signals to run the Transmit or Receive Shift
registers during Sleep.
Synchronous Slave mode uses an externally generated
clock to run the Transmit and Receive Shift registers.
16.4.1
To receive during Sleep, all the following conditions
must be met before entering Sleep mode:
• RCSTA and TXSTA Control registers must be
• If interrupts are desired, set the RCIE bit of the
• The RCIF interrupt flag must be cleared by read-
Upon entering Sleep mode, the device will be ready to
accept data and clocks on the RX/DT and TX/CK pins,
respectively. When the data word has been completely
clocked in by the external device, the RCIF interrupt
flag bit of the PIR1 register will be set, thereby waking
the processor from Sleep.
Upon waking from Sleep, the instruction following the
SLEEP instruction will be executed. If the Global
Interrupt Enable (GIE) bit of the INTCON register is
also set, then the Interrupt Service Routine at address
0004h will be called.

To transmit during Sleep, all the following conditions
must be met before entering Sleep mode:
• RCSTA and TXSTA Control registers must be
• The TXIF interrupt flag must be cleared by writing
• If interrupts are desired, set the TXIE bit of the
Upon entering Sleep mode, the device will be ready to
accept clocks on TX/CK pin and transmit data on the
RX/DT pin. When the data word in the TSR has been
completely clocked out by the external device, the
pending byte in the TXREG will transfer to the TSR and
the TXIF flag will be set, thereby waking the processor
from Sleep. At this point, the TXREG is available to
accept another character for transmission, which will
clear the TXIF flag.
Upon waking from Sleep, the instruction following the
SLEEP instruction will be executed. If the Global
Interrupt Enable (GIE) bit is also set then the Interrupt
Service Routine at address 0004h will be called.
