RE: Re[2]: Internal 1-Wire bus question

Pavel -

I think there I some un-used space in the DS2502, so users could do
something like "name" a device using that space. Of course, the reason
why the internal OW bus was brought off the edge of the SIMM was so that
users could have DS2502-type devices on their base platform and the TINI
could figure out what it was plugged into by reading that.

Hello Bryan,

Thanks, Bryan! (also thanks to Chris, who answered me off-list) And so,
another little question: is this feature using only on factory to
program DS2502 onboard, or this feature can be useful for an end-user.
As I know, DS2502 stores only MAC address and some configuration
information, isn't it?
