Hi,

 

I am using MC9S08SG16. I already selected "Initilize Trim Value"in CodeWarrior device initialization. Now my questions are:

 

1, Since the trim value in 0xFFAF is 0x80 already set, how accurate can the frequency reach using this setting?

2, Do I ahve to recalculate trim value? if yes, how to?

 

Thanks,
