HwMode IDs are stored and accessed in a bit set format, enabling users to efficiently retrieve specific IDs, such as the RegInfo HwMode ID, from the set as required.
Using this approach, various types of HwMode IDs can be added to a subtarget to manage different attributes within that subtarget, significantly enhancing the scalability and usability of HwMode. Moreover, to ensure compatibility, this method also supports controlling multiple attributes with a single HwMode ID, just as was done previously.
