Hi @mitchellpontague,

Thanks for taking the time to submit this pull request!

I'm not sure if this new functionality should be contained in the core. What you you think about making a new Arduino library (SAMD specific) for it?

I'd also love to see a library, it could be also made multi-architecure/multi-board using the boards/architecture defines.

@mitchellpontague hi, can you make a library for that? or do you need help for it?

I require this feature and I have created a library based in the work of @mitchellpontague , welcome feedback https://github.com/ElectronicCats/ElectronicCats_InternalTemperatureZero

Thanks @mitchellpontague
