USB-TO-GPIO2: Adapter Configuration for Open Drain

Part Number: USB-TO-GPIO2

Tool/software:

I am trying to use the USB-TO-GPIO2 adapter to debug a part embedded in a design. Because the part is using a 1.8V I/O rail I need the adapter to be operating as open drain.

However even when I set the device to open drain I see a pull up resistance to the 3.3V rail of about 10k.

I am also unable to set the GPIO control lines high on control 2 and 4 for a seemingly unrelated issue.

Does the Fusion Digital Power Designer support the USB-TO-GPIO2 interface adapter or is only the previous USB-TO-GPIO adapter compatible with the GUI?
