Figure 6.9. 10-Bit ADC0 Window Interrupt Example: Left Justified Differential Data
Given:
AMX0SL = 0x00, AMX0CF = 0x01,
AD0LJST = ‘1’,
ADC0LTH:ADC0LTL = 0x2000,
ADC0GTH:ADC0GTL = 0xFFC0.
An ADC0 End of Conversion will cause an
ADC0 Window Compare Interrupt (AD0WINT
= ‘1’) if the resulting ADC0 Data Word is
< 0x2000 and > 0xFFC0. (2s-complement
math.)
