  * @version 3.2.2
  * @date    08-July-2015
  * @brief   This file provides all the low level API to manage SPIRIT GPIO.
  * 
 * @details
 *
 * This module can be used to configure the Spirit GPIO pins to perform
 * specific functions.
 * The structure <i>@ref gpioIRQ</i> can be used to specify these features for
 * one of the four Spirit Gpio pin.
 * The following example shows how to configure a pin (GPIO 3) to be used as an IRQ source
 * for a microcontroller using the <i>@ref SpiritGpioInit()</i> function.
 *
 * <b>Example:</b>
 * @code
 *
 * SGpioInit gpioIRQ={
 *   SPIRIT_GPIO_3,
 *   SPIRIT_GPIO_MODE_DIGITAL_OUTPUT_LP,
 *   SPIRIT_GPIO_DIG_OUT_IRQ
 * };
 *
 * ...
 *
 * SpiritGpioInit(&gpioIRQ);
 *
 * @endcode
 *
 * @note Please read the functions documentation for the other GPIO features.
 *
