The DAC output pin keeps "disabled" during RESET period, the Reference

manual says.

So I will supply some DC on the DAC pin to check and adjust the Analogue

circuit surrounding the MCU at very beginning of the development.


What does "disable" mean?

If it means uncontrol and HIGH IMPEDANCE, my method may acceptable.

If not, DC supply may cause any troubles on the MCU chip.


GIVE me a correct Answer please.
