I am toggling a port but i observe a rise and fall time in digital output the micro used is ST and it is custom board. How do i rectify the issue? The switching is done at every 10KHz. Does it mean the PCB is not proper and has high capacitance?

Where do you suppose the fall time would be? If this is the leading edge of a sine wave
Then.....
