*    Description:    This routine disables the I2C2 module by 
*                    clearing the I2CEN bit in I2C2CON register.
*                    The MI2C2 and SI2C2 interrupts are disabled and 
*                    the corresponding IF flags are cleared
*    Parameters:     void                                   
*    Return Value:   void
