I'm using PSoC 5LP CY8C5888AXI-LP096.
When I put a scope at the 2 pins I'm geting the attached picture.
Why the level of the DAC rise up when the P3_1 change.
Depending on your description, I create a project, but I don't find the issue you report.
If needed, add your test project and DAC output screenshot.
