i am using s32k144,
i want to make a GPIO pin as input so that i can get external level on this pin.
i will connect a series resistor with the pin to limit the current.
i have a question,what's the value of series resistor ?
can i use a 1MΩ resistor?
I want to know that what's the minimum crrent does the input GPIO pin need?
