GPIO20

PORT2LED2

PORT2_LED2_POL

To enable LED operation with either a

pull-up or pull-down, LED Polarity

takes on the inverted value of the

configuration strap. Refer to Section

5.17, "LEDs" and Section 3.3.5, "LED

Polarity (PORT[3:0]_LED[2:1]_POL)"

for additional information.

Note:

The following must be considered when using GPIOs:

• Configuring a pin as a GPIO input automatically enables an internal pull-up.

• Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal resistors to

drive signals external to the device. When connected to a load that must be pulled high, an external

resistor must be added.

• Configuring a pin as a GPIO output automatically disables the internal pull-up. Open-drain outputs

may require an external pull-up depending on the application.
