-/**
- * \file
- *
- * \section Purpose
- *
- * This file provides a basic API for PIO configuration and usage of
- * user-controlled pins. Please refer to the board.h file for a list of
- * available pin definitions.
- *
- * \section Usage
- *
- * -# Define a constant pin description array such as the following one, using
- * the existing definitions provided by the board.h file if possible:
- * \code
- * const Pin pPins[] = {PIN_USART0_TXD, PIN_USART0_RXD};
- * \endcode
- * Alternatively, it is possible to add new pins by provided the full Pin
- * structure:
- * \code
- * // Pin instance to configure PA10 & PA11 as inputs with the internal
- * // pull-up enabled.
- * const Pin pPins = {
- * (1 << 10) | (1 << 11),
- * REG_PIOA,
- * ID_PIOA,
- * PIO_INPUT,
- * PIO_PULLUP
- * };
- * \endcode
- * -# Configure a pin array by calling PIO_Configure() with a pointer to the
- * array and its size (which is computed using the PIO_LISTSIZE macro).
- * -# Change and get the value of a user-controlled pin using the PIO_Set,
- * PIO_Clear and PIO_Get methods.
- * -# Get the level being currently output by a user-controlled pin configured
- * as an output using PIO_GetOutputDataStatus().
