MPC5744 PLL Configuration and PLL1 Frequency Calculate

When I read the demo "Hello_World_PLL_Interrupt_MPC577P", I found that the PLL1 Frequency Calculate result does not equal to that the PRM mentioned.I do not know how to understand it. Please tell me how to understand it .Sincere thanks!!

Hello,

I cant comment on Hello world SW as I am not familiar with it.

But I can say, RM is correct. So probably example is not.

You can use our calculator to ease the work with clocks on this device:

Which is aligned with reference manual.

We have also posted a ton of examples here:

Best regards,
