*    Function Name : OpenDCI									
*    Description   : This routine configures: the DCICON1 register which 
*                    contains information about Enable bit, Frame Sync mode, 
*                    Data Justification, Sample Clock Direction, Sample Clock 
*                    Edge Control, Output Frame Synchronization Directions 
*                    Control, Continuous Transmit/Receive mode, Underflow mode.
*
*                    DCICON2 register which contains the Frame Sync Generator 
*                    Control, Data Word Size bits, Buffer Length control bits.
*
*                    DCICON3 which contains the clock generator control bits.
*
*                    TSCON which contains the  transmit time slot enable control bit.
*
*                    RSCON which contains the receive time slot  enable control bit .
*
*    Parameters   :  unsigned int : config1
