Hi Llitha.

We do not have any example code that is specific to the LM3S3749. If an NTSC or PAL composite input is connected to the AIP1A input, setting up I2C register 03h should be all that is requied to provide an ITU bt.656 YCbCr output.

I2C register address 03h = 09h // Miscellaneous controls register address. Enables YCbCr output and the clock output

We do, however, recommend using the latest patch code in your final design to include all of the latest firmware improvements. This requires download of the patch code following power-up and Reset.

The latest patch code and procedure can be found at:

V048CAA is the version most typically used.
