ADC0LTH:ADC0LTL

AD0WINT=1

ADC0GTH:ADC0GTL

AD0WINT

not affected

-REF

0xF800

Given:

AMX0SL = 0x00, AMX0CF = 0x01,

AD0LJST = ‘0’,

ADC0LTH:ADC0LTL = 0x0100,

ADC0GTH:ADC0GTL = 0xFFFF.

An ADC0 End of Conversion will cause an

ADC0 Window Compare Interrupt (AD0WINT

= ‘1’) if the resulting ADC0 Data Word is

< 0x0100 and > 0xFFFF. (In two’s-complement

math, 0xFFFF = -1.)
