1.3 Internal Pull-up and Pull-down Pins
Some pins of the device package are connected to internal pull-up and pull-down resistors. When
these pins are Not Connected (NC) on the system board, these resistors set the default value for
input and sample at reset configuration pins.
The internal pull-up and pull-down resistor value is 50 kΩ. An external resistor with a lower value can
override this internal resistor.
