I have a problem with PLL:
uC works with Crystal 25MHz and PLL multiply by two (devide 8 [predivider] and then multiply by 16[MRD]) , so should be 50MHz.
Sometimes The uC wakes up in correct frequency(50MHz) but sometimes runs faster...
Does anybody have that problem with this uC?
The same program on MCF52234 works perfect - always wakes up with 50MHz
Crystal works properly - 25MHz on EXTAL, PCB is correct, all peripheral capacitors are correct...
I think it must be problem of uC...
