Chapter 13 Analog-to-Digital Converter (ADC12B16CV1)
13.3.2.12 ATD Conversion Result Registers (ATDDRn)
The A/D conversion results are stored in 16 result registers. Results are always in unsigned data
representation. Left and right justification is selected using the DJM control bit in ATDCTL3.
If automatic compare of conversions results is enabled (CMPE[n]=1 in ATDCMPE), these registers must
be written with the compare values in left or right justified format depending on the actual value of the
DJM bit. In this case, as the ATDDRn register is used to hold the compare value, the result will not be
stored there at the end of the conversion but is lost.

result registers. Compare is always done using all 12 bits of both the conversion result and the compare
value in ATDDRn.

shows how depending on the A/D resolution the conversion result is transferred to the ATD
For conversions not using automatic compare, results are stored in the result
registers after each conversion. In this case avoid writing to ATDDRn except
for initial values, because an A/D result might be overwritten.
