The answer to your question:

Yep. (Texan for Yes)

Its a little tricky because you need to be able to use the port pin bi-directionally (input and output).

The hard thing is its critical timing.
The microprocessor must be able to control and read the port lines very quickly which can effect the way you use interrupts. SPI or I2C interfaces are much more easy to tolerate higher level interrupt processing than 1-wire. This might be reason enough to examine a different component.

I personally don't see any real advantage to 1-wire interfaces for internal components.

The 1 wire protocol is the same basic stuff as their "iButton" protocol. Its similar to I2C but a little more complex.

iButtons are really easy to communicate with unless you get fooled into using their pre-packaged "TMEX" software. I know a couple of companies that used that and made a mess of their design.

Tomorrow when I get to the office, I'll look up the appropriate URL to their PDF file application notes.

iButtons: Been there, done that.

Maybe someday I'll post the massive security hole about using iButton technology.

Well... only after I stop selling them in my product line. :)
