7178 - CertusPro-NX: Why are FPGA I/O lines "zero" by default? How to pull them to 'high' by default?

7178 - CertusPro-NX: Why are FPGA I/O lines "zero" by default? How to pull them to 'high' by default?

CertusPro-NX's I/O hardware default is weak pull-down, and it cannot be changed until it is powered up and loaded with bitstream. 
The only way to get those lines to be 'high' by default is by adding external pull-up resistor on the PCB board.
