AUSART Baud Rate Generator
(BRG)
The Baud Rate Generator (BRG) is an 8-bit timer that
is dedicated to the support of both the asynchronous
and synchronous AUSART operation.
The SPBRG register determines the period of the free
running baud rate timer. In Asynchronous mode the
multiplier of the baud rate period is determined by the
BRGH bit of the TXSTA register. In Synchronous mode,
the BRGH bit is ignored.
Table 16-3 contains the formulas for determining the
baud rate. Example 16-1 provides a sample calculation
for determining the baud rate and baud rate error.
Typical baud rates and error values for various
asynchronous modes have been computed for your
convenience and are shown in Table 16-5. It may be
advantageous to use the high baud rate (BRGH = 1), to
reduce the baud rate error.
Writing a new value to the SPBRG register causes the
BRG timer to be reset (or cleared). This ensures that
the BRG does not wait for a timer overflow before
outputting the new baud rate.
EXAMPLE 16-1:
CALCULATING BAUD
RATE ERROR
For a device with FOSC of 16 MHz, desired baud rate of
9600, and Asynchronous mode with SYNC = 0 and BRGH
= 0 (as seen in Table 16-5):
