I'm trying to run a chip at 4MHz (doesn't have to but I just want to for now).
It seems that the smallest mutiplier is 4 (8MHz), if I use 2 then the PLL is never ready and the code just hangs, any other value works ok.
So is it better running the PLL at a higher frequency and then use a divider?
Yeah, I know it's in the manual somehwere... :)
edit actually 3 also works (6MHz)
