[765208638]

Dear everyone & NXP engineers:

   I am very happy to use HC9S08SG to do my job.I have a question about it's FLL(FEE).

In doc《AN3041》,

We can see it is  multiply by 512.

and when useing  PE on CW6.3,as below

we can see it is multiply by 1024,so i am a bit confused.Maybe i did not read the ducument carefully?

So ,could you everyone please help me about this question.

At lasy ,my english is not good ,please forgive me .

Thanks all.

Hi. AN3041 applies to the first version of the Internal Clock Source (ICS). You need to check the datasheet for the version that is in the MCU you are using. The SG32 and SG8 MCUs multiply the reference by 1024, as shown in the PE window.

John
