AFAIK Pavel highlighted this problem when we discussed possible interface chips and we really didn't want to have persistent state that could be altered from the external interface. If you think it will not add any time in schematics and layout, add the footprint. But otherwise I suggest not doing this. - -- Med vänlig hälsning, Yours Joachim Strömbergson - Alltid i harmonisk svängning. ======================================================================== Joachim Strömbergson Secworks AB joac...@secworks.se ======================================================================== -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBCAAGBQJWswoCAAoJEF3cfFQkIuyNPUYP/jCAxDmRDf6lGeVk2vfrTiXo PmgWySJ/9l9zQxHsFdF/fvleUmp2swjaO3aQWNCeRMJtrgTj5eBvCb3lBNYcS1Mu zne794ZtZDy4n8AYVxF5EurYj9ngXAy3LlydQP4ORM2+6fjkUZIDU/0TvmMWXG7v vcGoUoPMkpMSiIdTPEV9CCPTvV6590Y44P/IqLro6Ut0LAjbE7NwGttAfhRTeCOn nYHGmgk5BiIQUvrpYVO2a6wq7BOgBd3shcSKfIB7KlafEBxL66MIJTfaVrb4K33v 3dJ5/75T7VsCw6GgEKRmpM/vbJWqR8v69AKa5G5nSbLywXC8WhEyWFGPWRTWMhIW MvIDeWAFp8Eed5nKDNriOYntimw1O+Oi+EeHUmCZag1xC5A1idd5LwNds5J2jtBu nUase/LGTwGijXdBRq6haPWijgP/RBeffEb5zMhMEkZO3PGL+rLE86fWKUPEO7b/ ttVFI7gA2GmXoT7XK0CpinG8/TvUEyuD7jk0k9E2ciWcn0Su/jw7B6mHQ2pbRDTW S4WcRszGlIcM9v9gTr1YsHZebtRWHfIgl6lsKADwDoWTTb7Djv4ZgwBNVB8309mR jn2qF9r+XJQRcn6v2jxdHW0n9+tOTzs5TAAchAqPYUbbfeXW732I2KxSq/5m2VXJ Kq1Bd9nHSaT6iRfgEf1F =gTAd -----END PGP SIGNATURE----- _______________________________________________ Tech mailing list Tech@cryptech.is https://lists.cryptech.is/listinfo/tech
