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.

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: Read-only bits, always read as 1.
