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
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
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 is controlled individually.
When the DAE bit 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 20.2 below.
