22.2
The BRG is a dedicated, 8-bit or 16-bit generator that
supports both the Asynchronous and Synchronous
modes of the EUSART. By default, the BRG operates
in 8-bit mode; setting the BRG16 bit (BAUDCONx<3>)
selects 16-bit mode.
The SPBRGHx:SPBRGx register pair controls the period
of a free-running timer. In Asynchronous mode, bits,
BRGH (TXSTAx<2>) and BRG16 (BAUDCONx<3>),
also control the baud rate. In Synchronous mode, BRGH
is ignored.
of the baud rate for different EUSART modes which only
apply in Master mode (internally generated clock).
Given the desired baud rate and F
integer value for the SPBRGHx:SPBRGx registers can
be calculated using the formulas in
the error in baud rate can be determined. An example
calculation is shown in
and error values for the various Asynchronous modes
are shown in

the high baud rate (BRGH = 1 ) or the 16-bit BRG to
reduce the baud rate error, or achieve a slow baud rate
for a fast oscillator frequency.
Writing a new value to the SPBRGHx:SPBRGx regis-
ters causes the BRG timer to be reset (or cleared). This
ensures the BRG does not wait for a timer overflow
before outputting the new baud rate.
22.2.1
The device clock is used to generate the desired baud
rate. When one of the power-managed modes is
entered, the new clock source may be operating at a
different frequency. This may require an adjustment to
the value in the SPBRGHx:SPBRGx register pair.
22.2.2
The data on the RXx pin (either RC7/CANRX/RX1/DT1
or RB7/PGD/T3G/RX2/DT2/KBI3) is sampled three
times by a majority detect circuit to determine if a high
or a low level is present at the RXx pin.
