  * 
  * **Detailed Description :**
  * 
  * This header file for pin control is based on the most common configuation options
  * curenty awailable for modern hardware. 
  * Depending of the used Chip, some function may vary or be unawailable. 
  * Please take a minute to go and explore the according Chips pin.c file to see woh each function 
  * is implmented.  
  *
  * @todo
