Figure 6.18. 10-Bit ADC0 Window Interrupt Example: Left Justified Single-Ended Data
Given:
AMX0SL = 0x00, AMX0CF = 0x00, ADLJST = 1,
ADC0LTH:ADC0LTL = 0x8000,
ADC0GTH:ADC0GTL = 0x4000.
An ADC End of Conversion will cause an ADC
Window Compare Interrupt (ADWINT=1) if the
resulting ADC Data Word is < 0x8000 and
> 0x4000.
