3.11.1
Both UART modules have their own dedicated baud-rate generator, which is based on
a programmable 8-bit reload value, and includes divider stages (i.e., prescaler and
fractional divider) for generating a wide range of baud rates based on its input clock
f
PCLK
, see

Baud-rate Generator Circuitry
The baud rate timer is a count-down timer and is clocked by either the output of the
fractional divider (f
MOD
) if the fractional divider is enabled (FDCON.FDEN = 1), or the
output of the prescaler (f
DIV
) if the fractional divider is disabled (FDEN = 0). For baud rate
generation, the fractional divider must be configured to fractional divider mode
(FDCON.FDM = 0). This allows the baud rate control run bit BCON.R to be used to start
or stop the baud rate timer. At each timer underflow, the timer is reloaded with the 8-bit
reload value in register BG and one clock pulse is generated for the serial channel.
Enabling the fractional divider in normal divider mode (FDEN = 1 and FDM = 1) stops the
baud rate timer and nullifies the effect of bit BCON.R. See
Section 3.12
.
The baud rate (f
BR
) value is dependent on the following parameters:
