I can't really parse what you're talking about here (perhaps some of that context would have helped...) but it doesn't seem to be the clocking of the I2S bus which would normally be what master and slave would be talking about. If it's something else perhaps the code needs to be clarified to make it clear that it's not talking about the bus. --fKov5AqTsvseSZ0Z Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl5mgkQACgkQJNaLcl1U h9A5Fgf/Urnfg3j5PZES06ywstEE7IyxgzPd7YpkYqxz2XToPpUnbB1SBhF0Lfxk xo/iCZDUkh8H259e98Hq1BEN/mB8UROBB4E23KAY/cYsoFYjU3ZQQtGL3InblMsO 6fFx4mnUIX47TvK9S5oIsXpsS/+mrTx5GPmY9Xg/gBy32d15wnNFYtGP9mCGEgOi hRj/VQ2vuAbiHk0D3Qjd6GvUZMnvF88BMndqq8wtUMjnwPK5pfk3SD62n1dQkuov 5MClefdJR/qwrpfLHjEzOzfSqrRceYcim8ccxQHmU/5qHgBm2xMTQFQeBjTLWIFs 7Qdtn3SNwtwyrW55Xp9IrO2+zHwjJw== =VLrd -----END PGP SIGNATURE----- --fKov5AqTsvseSZ0Z--
