Description
D/A Output Enable 1
Controls D/A conversion and analog output
0: Analog output DA1 is disabled
1: D/A conversion for channel 1 and analog output DA1 are
D/A Output Enable 0
Controls D/A conversion and analog output
0: Analog output DA0 is disabled
1: D/A conversion for channel 0 and analog output DA0 are
D/A Enable
Controls D/A conversion in conjunction with the DAOE0
and DAOE1 bits. When the DAE bit is cleared to 0, D/A
conversion for channels 0 and 1 are controlled individually.
When DAE is set to 1, D/A conversion for channels 0 and 1
are controlled as one. Conversion result output is controlled
by the DAOE0 and DAOE1 bits. For details, see table 18.2.
Reserved
These bits are always read as 1 and cannot be modified.
