The advantage of bit fields is that they can pack more information into a given amount of memory.
The disadvantage of bit fields is that they typically take longer to access than the integer types unless the target processor has bit-resolution assembly instructions.

Real-Time applications are generally willing to accept increased memory usage for faster execution
