Description
D/A Output Enable 3
Controls D/A conversion and analog output.
0: Channel 3 analog output (DA3) is disabled.
1: Channel 3 D/A conversion is enabled; channel 3
D/A Output Enable 2
Controls D/A conversion and analog output.
0: Channel 2 analog output (DA2) is disabled.
1: Channel 2 D/A conversion is enabled; channel 2
This bit is 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 19.2.
Reserved
These bits are always read as 1 and cannot be
modified.
analog output (DA3) is enabled.
analog output (DA2) is enabled.
