Nope! there's nothing wrong. I posted two at the same time to get the answer faster. Thanks for the answer
for all,
The answer by AKE is
1) The operating voltage is 1.8 V - 3.6 V. Within that span, the
component behaves normally, so no compensation is needed.
See Section 3.13 and Table 7 in MC9S08QE8.
2) I have no paper describing the 9S08QE8. The closest I got is the
9S08QG8, so I will send you a paper/file describing that MCU instead.
