While interfacing 10M08SCU169I7G with a MCU using a bidirectional bus, at a particular instant both side are need to set in input state. Does it damage any products when FPGA and MCU pins are both in input state?

Hi Sujisha,

As a designer, we need to control the IO Buffer output enable on the FPGA side.

The value of OE determines whether bidirectional pins is an input, feeding in input

, or a tri-state, driving out the value.
