What is saupādisesā according to the Pali suttas?

I have not read 100% of the Pali suttas. I am only aware of the term "saupādisesā" in the following sutta: > *“Bhikkhus, there are these two Nibbāna-elements. What are the two? The Nibbāna-element with residue left and the Nibbāna-element with no > residue left.* > > *“What, bhikkhus, is the Nibbāna-element **with residue/fuel (saupādisesā)** left? Here a bhikkhu is an arahant, one whose taints are destroyed, the holy life > fulfilled, who has done what had to be done, laid down the burden, > attained the goal, destroyed the fetters of being, completely released > through final knowledge. However, his five sense faculties remain > unimpaired, by which he still experiences what is agreeable and > disagreeable and feels pleasure and pain. It is the extinction of > attachment, hate, and delusion in him that is called the > Nibbāna-element with residue left.* > > *“Now what, bhikkhus, is the Nibbāna-element with no residue left? Here a bhikkhu is an arahant … completely released through final > knowledge. For him, here in this very life, all that is felt/experienced (*sabbavedayitāni*), not being delighted in, will be become cold (siti). That, bhikkhus, is > called the Nibbāna-element with no residue left.* > >*Iti 44* Based on the Pali suttas - without quoting any views of commentaries or scholars - what teachings exist in the Pali suttas that might explain the meaning of "*Nibbāna-element with residue (saupādisesā) left*"?
