Bit 6—D/A Output Enable 0 (DAOE0): Controls D/A conversion and analog output.

Bit 5—D/A Enable (DAE): Used together with the DAOE0 and DAOE1 bits to control D/A
conversion. When the DAE bit is cleared to 0, channel 0 and 1 D/A conversions are controlled
independently. When the DAE bit is set to 1, channel 0 and 1 D/A conversions are controlled
together.
Output of conversion results is always controlled independently by the DAOE0 and DAOE1 bits.
Bit 7
DAOE1

If the chip enters software standby mode when D/A conversion is enabled, the D/A output is held
and the analog power current is the same as during D/A conversion. When it is necessary to reduce
the analog power current in software standby mode, clear both the DAOE0 and DAOE1 bits to 0
to disable D/A output.
Bits 4 to 0—Reserved: These bits cannot be modified and are always read as 1.
