6.3.2.16
The A/D conversion results are stored in 16 read-only result registers. The result data is formatted in the
result registers bases on two criteria. First there is left and right justification; this selection is made using
the DJM control bit in ATDCTL5. Second there is signed and unsigned data; this selection is made using
the DSGN control bit in ATDCTL5. Signed data is stored in 2’s complement format and only exists in left
justified format. Signed data selected for right justified format is ignored.
Read: Anytime
Write: Anytime in special mode, unimplemented in normal modes
