/************************************************************************
*    Function Name:  MasterWriteI2C1
*    Description:    This routine is used to write a byte to the I2C bus.
*                    The input parameter data_out is written to the 
*                    I2CTRN register. If IWCOL bit is set,write collision 
*                    has occured and -1 is returned, else 0 is returned.             
*    Parameters:     unsigned char : data_out                                   
*    Return Value:   char
