If the automatic wake-up and the external wake-up need to be the same time, we need to use the
appropriate line logic operation circuit when the external circuit is designed.

What exactly is meant here by "the appropriate line logic operation circuit"? Is this circuit designed by the designer, or is there some sort of functionality provided by the SDK?
