How to set DAC (ADuC7060/7061) to 0 on the external reset and programming?
During a reset sequence or when programming the part, the DAC will go to its default state.
By default, the DAC output is disabled - high impedance. So if you want to ensure the DAC is at a low level, add a weak pull-down resistor to the DAC output. (47K should be fine).
