hi

Could you show me how to configure pull up/down GPIO pin when it is external interrup , I tried to use funtion 

GPIOPadConfigGet (uint32_t ui32Port, uint8_t ui8Pin, uint32_t ∗pui32Strength, uint32_t
∗pui32PinType)

and

GPIOPadConfigSet (uint32_t ui32Port, uint8_t ui8Pins, uint32_t ui32Strength, uint32_t
ui32PinType)

but it not work , so I used GPIOPinConfigure but i see my data is noise;
