When the D/A converter is not used, set the DAiE bit (i = 0 or 1) to 0 (output disabled) and set the DAi register
to 00h to prevent current from flowing into the R-2R resistor ladder to reduce unnecessary current consumption.
When the D/A converter is not used, set the DAiE bit (i = 0 or 1) to 0 (output disabled) and set the DAi register
