Overview

Provides input-only support for an MCUXpresso GPIO pin.

Class-specific behaviors:

The input buffer for the pin must be enabled in the IO Pad Controller (IOPCTL) via the Input Buffer Enable (IBENA) bit.
The input polarity is affected by the Input Invert Enable (IIENA) bit on the corresponding IO Pad Controller (IOPCTL) register.
