I am trying to program the M48T35 from SL. To be more precise just the time.

How to program the time is explained in the data sheet.

To do this, you have to manipulate individual bytes. Is it possible to include an option that only allows you to write a single byte or does the fireware not allow that?

Thanks

That sounds interesting and potentially useful!

As far as I can tell from the minipro source, the programmer can definitely do this. It does this for IC testing, for instance. It can either leave pins floating, or drive them (high or low). It's just a matter of doing this in the right sequence, but I don't think an appropriate programming driver is available for timekeeper ICs. Yet.
