Hi, TI Support Team

The review is in progress by referring to the document www.ti.com/.../slva645.

Regarding LOD function, "3.8.3 Suggested LED Open Detection Process" guides as follows.

Is setting GS=FFFF mandatory?

Can I put in another value?

If you can put a different value, please tell me how to set it.

Thanks.

Hi MJ,

Since the LOD data output by detect circuit are valid only during the ‘on’ period of that OUTXn output channel. LOD data are always ‘0’ for outputs that are turned off. so it is necessary to setting GS=FFFF when operate LOD funciton.
