I will add here that the manual is quite correct ;)  I've had the PLL 
programmed incorrectly and the only obvious effect was to make the serial 
baud rate rather odd.  Otherwise the micro seemed to be operating properly 
and at the correct speed.  I suspect the side effect can be even more 
subtle than that.
