17.1
The UART module includes a dedicated 16-bit Baud
Rate Generator. The BRGx register controls the period
of a free-running 16-bit timer. Equation 17-1 shows the
formula for computation of the baud rate with
BRGH = 0.
EQUATION 17-1:
Example 17-1 shows the calculation of the baud rate
error for the following conditions:
• F
• Desired Baud Rate = 9600
The maximum baud rate (BRGH = 0) possible is

Equation 17-2 shows the formula for computation of
the baud rate with BRGH = 1.
EQUATION 17-2:
The maximum baud rate (BRGH = 1) possible is F
(for BRGx = 0), and the minimum baud rate possible is
F
Writing a new value to the BRGx register causes the
BRG timer to be reset (cleared). This ensures the BRG
does not wait for a timer overflow before generating the
new baud rate.
