20.5 Usage Note
When this LSI enters software standby mode with D/A conversion enabled, the D/A output is
retained, and the analog power supply current is equal to as during D/A conversion. If the analog
power supply current needs to be reduced in software standby mode, clear the DAOE1, DAOE0,
and DAE bits all to 0 to disable D/A output.
