ADUC834: Does changing the PLL divider value via the CD bits in PLLCON affect the baud rate?

Q 

Does changing the PLL divider value via the CD bits in PLLCON affect the baud
rate?

 

A 

Yes, changing the CD bits does affect the baud rate. The output of the PLL
divider is the core
clock frequency which the baud rates are obtained from. See the ADuC834
datasheet (pg 62/63)
for more details.
