PIC18F85J90 FAMILY
18.2
The BRG is a dedicated, 8-bit generator that supports
both the Asynchronous and Synchronous modes of the
AUSART.
The SPBRG2 register controls the period of a
free-running timer. In Asynchronous mode, bit BRGH
(TXSTA<2>) also controls the baud rate. In Synchro-
nous mode, BRGH is ignored. Table 18-1 shows the
formula for computation of the baud rate for different
AUSART modes, which only apply in Master mode
(internally generated clock).
Given the desired baud rate and F
integer value for the SPBRG2 register can be calcu-
lated using the formulas in Table 18-1. From this, the
error in baud rate can be determined. An example
calculation is shown in Example 18-1. Typical baud
rates and error values for the various Asynchronous
modes are shown in Table 18-2. It may be advanta-
geous to use the high baud rate (BRGH = 1) to reduce
the baud rate error, or achieve a slow baud rate for a
fast oscillator frequency.

Writing a new value to the SPBRG2 register 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.
18.2.1
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 SPBRG2 register.
18.2.2
The data on the RX2 pin is sampled three times by a
majority detect circuit to determine if a high or a low
level is present at the RX2 pin.
