hello everyone i am  trying to send some digital value Using I2C 
protocol from DSP 2833x (Master)to DAC MCP47x6A0T-E/xx (Slave). Although 
program isnt showing any error but when i check the data line i dont see 
any data on it.  Below is my program. Kindly help me in this regard. 
Your response will be highly appreciated.
