UART fractional divider

Do any code examples exist for using the fractional divider with ADuc 7061?


Switching to an external clock i have very accurate and stable PWM timings so i believe my clock is very close to 10.24MHz however i now have UART baud rate issues appearing on an attached external LCD panel. Using the internal oscillator my PWM periods were longer than expected (calculated) due to +-3% error but i had no baud rate issues - this seem a little contrary.

I believe the 450 UART normally runs 1.01% fast with the internal oscillator but this seemed to work OK.
