design choice is the isolation of programming pins from their alternate

I believe for the programming, and that doesn't leave much for else. How

would one go about isolating these pins functions from their alternate tasks?

For my project, there will be one stepper motor driven via a L293N, and I think

that is going to require at least 4 pins of the tiny45, then another couple for

analog inputs to figure when to start and stop driving the stepper...How does

one go about keeping these isolated from the programming functions? Other than

using jumper pins and having to manually switch shunts each time I want to

program?(Although that could work for my purpose, I would like a more robust

  solution..) Thanks in advance, Jaydag71
