16.3.15 UART Fractional Precision Divider Control Registers (UFPDn)
The UFPDn registers allow greater accuracy when deriving a transmitter/receiver clock source from
CLKIN. The use of the UFPDn registers is optional; if the contents are left in the reset state, code written
for other ColdFire devices containing UART modules will not be affected by the addition of these
registers. The contents of these registers allow the frequency to be divided by a factor of up to 16. When
autobaud is used, these registers are updated automatically to reflect the clock rate being used. Host
software can write to these registers to make fine adjustments to the clock rate. See

Fractional divider. The value of these bits, from 0 to 15, determine the scale factor by which the clocking source
for the transmitter and/or receiver is scaled.
