D/A Output Enable 3
Controls D/A conversion and analog output.
0: Analog output (DA3) is disabled
1: Channel 3 D/A conversion is enabled; analog output
D/A Output Enable 2
Controls D/A conversion and analog output.
0: Analog output (DA2) is disabled
1: Channel 2 D/A conversion is enabled; analog output
Used together with the DAOE2 and DAOE3 bits to
control D/A conversion. When the DAE bit is cleared to
0, channel 2 and 3 D/A conversions are controlled
independently. When the DAE bit is set to 1, channel 2
and 3 D/A conversions are controlled together.
Output of conversion results is always controlled
independently by the DAOE2 and DAOE3 bits. For
details, see table 18.3.
These bits are always read as 1 and cannot be modified.
