The ADRES register contains the results of the last
conversion. These results are present during the sam-
pling period of the next analog conversion process.
After the sampling period is over, ADRES is cleared
(= 0). A ‘leading one’ is then right shifted into the
ADRES to serve as an internal conversion complete
bit. As each bit weight, starting with the MSB, is con-
verted, the leading one is shifted right and the con-
verted bit is stuffed into ADRES. After a total of 9 right

When the ANS bits are set, the channels selected will automatically be forced into Analog mode, regard-
less of the pin function previously defined. The only exception to this is the comparator, where the analog
input to the comparator and the ADC will be active at the same time. It is the users responsibility to ensure
that the ADC loading on the comparator input does not affect their application.
The ANS<1:0> bits are active regardless of the condition of ADON.
CHS<1:0> bits default to 11 after any Reset.
If the ADON bit is clear, the GO/DONE bit cannot be set.

shifts of the ‘leading one’ have taken place, the conver-
sion is complete; the ‘leading one’ has been shifted out
and the GO/DONE bit is cleared.
If the GO/DONE bit is cleared in software during a con-
version, the conversion stops. The data in ADRES is
the partial conversion result. This data is valid for the bit
weights that have been converted. The position of the
‘leading one’ determines the number of bits that have
been converted. The bits that were not converted
before the GO/DONE was cleared are unrecoverable.
