SKR 1.4 turbo endstop pullup not working

Hello, I am unable to make the end stop working at SKR 1.4 turbo. The end stop looks like there is no pull-up on the pin the default voltage on the input pin is 0V. I tried changing the settings to $18 but still no voltage. If I invert the pin status and connect 3.3V to limit input it is detected as pressed endstop. Thanks a lot.
