signals from RS-232 to TTL levels also perform an inver-
buffering without inverting the signal.

20.2.2
The receiver block diagram is shown in Figure 20-6.
The data is received on the RXx pin and drives the data
recovery block. The data recovery block is actually a
high-speed shifter operating at x16 times the baud rate,
whereas the main receive serial shifter operates at the
bit rate or at F
in RS-232 systems.
The RXDTP bit (BAUDCON<5>) allows the RXx signal
to be inverted (polarity reversed). Devices that buffer
sion of the signal (when RS-232 = positive, TTL = 0).
Inverting the polarity of the RXx pin data by setting the
RXDTP bit allows for the use of circuits that provide

Initialize the SPBRGHx:SPBRGx registers for
the appropriate baud rate. Set or clear the
BRGH and BRG16 bits, as required, to achieve
the desired baud rate.
Enable the asynchronous serial port by clearing
the SYNC bit and setting bit, SPEN.
If the signal at the RXx pin is to be inverted, set
the RXDTP bit.
If interrupts are desired, set enable bit, RCxIE.
If 9-bit reception is desired, set bit, RX9.
Enable the reception by setting bit, CREN.
Flag bit, RCxIF, will be set when reception is
complete and an interrupt will be generated if
enable bit, RCxIE, was set.
Read the RCSTAx register to get the 9th bit (if
enabled) and determine if any error occurred
during reception.
