0-15 AD0CMP0-AD0CMP15 (Note 2)
(A-D0 comparate result flag)
Note 1: This register must always be accessed in halfwords.
Note 2: During comparator mode, each bit corresponds to channels 0 through 15.
When comparator mode is selected by setting the A-D0 Single Mode Register 1 AD0SMSL (A-D0
conversion mode selection) bit, the selected analog input value is compared with the value written
to the A-D0 Successive Approximation Register, with the result stored in the corresponding bit of
this comparate data register.
The bit is 0 when the analog input voltage > comparison voltage, and is 1 when the analog input
voltage < comparison voltage.
