The ADRES register contains the results of the last
conversion. These results are present during the
sampling 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
converted, the leading one is shifted right and the
converted bit is stuffed into ADRES. After a total of 9

right shifts of the ‘leading one’ have taken place, the
conversion 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
conversion, 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.
