I understand that. What if I2C had the same seperation between the "bus" and the "master"? --xesSdrSSBC0PokLI Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAlmAl7QACgkQFA3kzBSg Kbb7YxAAjX/3xJacOO47mGNmY2NRwlC9KXSIbzBsKNdiolaismhjNjUqJf1QSO3v fwYtarg7X26UYJ3JwsNfUV2d/Tqb6FD/1LT4C1KIFzKSPKKHGmYmRhhBs5H2qCnZ xctYRsWiyVtIj5gm0YxFayR158ju6tdJyP1v1wfPHt6t8bQ33Mp8qtX/ugjKzK0s ya7E63Ojxyv/LwUHujVZiWzwRFpvf+K9vigh2nVaV02jYNnqSu1zw7rME+ovUhLl mEnbrfRYh7ia8R3P3R48NE1l/ePOrRlLrQlRL7LP27FXHTxI3lmKmOv2er6kiXKP 8GErWKrudDbdc0Dxs0oC8V+6pmrysExNr28NXUsFgZWeLNlcETwCGO8mnOV3Qqhv fDCkvNFUkS4WFk8woxAdPph8uAw3pnNx8BPePIPZvVFvOb/Eu2JvreHfMFyhadAz 6fkSzgmIxSDQ9NijM3sr+e/7mGCJhzLDsmqKRwJFxWiKVRBmz3z9j1LjIkMIzcy6 obgOrn89g6Nkyi+Zqlx/GUJry7a/9od9DrSaLYtNZWbtIoVk1XT/BVlWtBzQJDdC P3JKSzWVKosJpBe/JQnajRFB2PwdhgwLz/gstTp2C94cSlQAqfA7cjUVDKUJaxFo k6Q47o2aQNbNRW4K8akkPFFSohIlsxlKLLmy2F2zSTqIRDz73+c= =CaK9 -----END PGP SIGNATURE----- --xesSdrSSBC0PokLI--
