\defgroup TIDC TIDC - TI daughter board initialization on IEKC64 board

        \brief This module is related configure a daugther board on TI connector provided by the IEKC64x.

   <h3> TIDC module </h3>

        <b> How does it work </b>
        
        This module configure CE space and reset function on the IEKC64x board
        
        <b> Reseting the daughter board </b>

        The TIDC_reset() function allow the user to reset the daugther board
        
        <b> Use full compatibility with TI standard </b>
        
        If you want to use large memory model withe the daugter board, you will need to set
        the A22 bit on the IEKC64x board with TIDC_setAG22() function
        
        <b> Configuring EMIF space used by the daughter board </b>
        
        The TIDC_setEmif() function set EMIF for space used by daughter board.
