Figure 5.18. 12-Bit ADC0 Window Interrupt Example: Left Justified Single-Ended Data
Given:
AMX0SL = 0x00, AMX0CF = 0x00,
AD0LJST = ‘1’,
ADC0LTH:ADC0LTL = 0x2000,
ADC0GTH:ADC0GTL = 0x1000.
An ADC0 End of Conversion will cause an ADC0
Window Compare Interrupt (AD0WINT = ‘1’) if
the resulting ADC0 Data Word is < 0x2000 and
> 0x1000.
