Description
DA analog output is disabled
1
Channel-1 D/A conversion and DA₁ analog output are enabled
Bit 6—D/A Output Enable 0 (DAOE0): Controls D/A conversion and analog output.

Description
DA analog output is disabled
0
Channel-0 D/A conversion and DA₀ analog output are enabled
Bit 5—D/A Enable (DAE): Controls D/A conversion, together with bits DAOE0 and DAOE1.
When the DAE bit is cleared to 0, analog conversion is controlled independently in channels 0
and 1. When the DAE bit is set to 1, analog conversion is controlled together in channels 0 and 1.
Output of the conversion results is always controlled independently by DAOE0 and DAOE1.

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