14.2.2.1
The ADC on MC9S08AW60 Series contains only two analog pin enable registers, APCTL1 and APCTL2.
14.2.2.2
The ADC is capable of running in stop3 mode but requires LVDSE and LVDE in SPMSC1 to be set.
14.2.3
The ADC1 module includes a temperature sensor whose output is connected to one of the ADC analog
channel inputs.
