MAX7000AE consumes high power on a Max3000A design

Hi, I am using a MAX3000A (EPM3032AT44-10) in a design running at fairly low speed (~1MHz). Since the Max3000 is obsolete now, I have migrated my design to the pin compatible type MAX7000AE (EP...

just wanted to add that the unused IO pins are connected to GND because I have kept the PCB layout.

Meanwhile my assumption is that the unused IOs are (somehow) driving HIGH but are tied to ground externally. At least that would explain the high current consumption. But how can I avoid this? I have enabled the global setting to configure unused ports as inputs. But maybe that does not have an effect. Do I have to declare the unused pins in my design and connect them to LOW or declare them as inputs?

Anybody got a clue?
