Bit 6—D/A Output Enable 0 (DAOE0): Controls analog output from the D/A converter.
Bit 6: DAOE0
Description
0
1
Analog output at DA0 is disabled.
D/A conversion is enabled on channel 0. Analog output is enabled at DA0.
Bit 5—D/A Enable (DAE): Controls D/A conversion, in combination with bits DAOE0 and
DAOE1. D/A conversion is controlled independently on channels 0 and 1 when DAE = 0.
Channels 0 and 1 are controlled together when DAE = 1.
The decision to output the converted results is always controlled independently by DAOE0 and
DAOE1.

When the DAE bit is set to 1, analog power supply current drain is the same as during A/D and
D/A conversion, even if the DAOE0 and DAOE1 bits in DACR and the ADST bit in ADSCR are
cleared to 0.
Bits 4 to 0—Reserved: These bits cannot be modified and are always read as 1.
