My PIC datasheet (PIC24HJ128GP202) specifies three parameters to configure the PLL which are N1, N2 and M. Each of them have to satisfy some clock frequencie ranges in input/output of each block inside the PLL. I looked all around the datasheet and did not found the answer for this question:
what happens if I do not respect these ranges?
I mean, in the final output for example. The frequency should be between 12.5 MHz and 80MHz. What happens if I select PLLPOST (N2) which leads me to 80.5 MHz? Or yet select a PLLDIV (M) which leads me to 201MHz (when PLLPOST intput should be between 100-200 MHz)?
