PLL N-Multiplier , K2-Divider Value

Hi

Now we using fSYS Clock at 40Mhz via N-Multiplier setting as '16' , and K2-Divider setting as'2'.(Int OSC 5Mhz)

so,Is it possible change the N, K2 value as '24' and '3' ?

I think there is same fSYS value(40Mhz) , but before N-Multiplier calculation value are different '16'(80Mhz) and '24'(120Mhz).

Is there any problem if we use these value?

and one more question,

if we using like it, is the VCO RANGE also changed to 96-160Mhz?

Would you check this one?

Thanks.
