Input Voltage
(AD0 - AD1)
REF x (2047/2048)
ADC Data
Word
0x7FF0
AD0WINT
not affected
REF x (256/2048)
REF x (-1/2048)
0x1010
0x1000
0x0FF0
0x0000
0xFFF0
0xFFE0
ADC0LTH:ADC0LTL
AD0WINT=1
ADC0GTH:ADC0GTL
AD0WINT
not affected
-REF
0x8000
Given:
AMX0SL = 0x00, AMX0CF = 0x01,
AD0LJST = ‘1’,
ADC0LTH:ADC0LTL = 0x1000,
ADC0GTH:ADC0GTL = 0xFFF0.
An ADC0 End of Conversion will cause an
ADC0 Window Compare Interrupt (AD0WINT
= ‘1’) if the resulting ADC0 Data Word is
< 0x1000 and > 0xFFF0. (Two’s-complement
math.)
