Section 29 D/A Converter
Bit 5—D/A Enable (DAE): Controls D/A conversion, together with bits DAOE0 and DAOE1.
When the DAE bit is cleared to 0, D/A conversion is controlled independently in channels 0 and 1.
When this LSI enters standby mode while D/A conversion is enabled, the D/A output is held and
the analog power-supply current is equivalent to that during D/A conversion. To reduce the analog
power-supply current in standby mode, clear the DAOE0 and DAOE1 bits and disable the D/A
output.

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.
