A quick question pertaining to preventing "tear", chip brick-age (if that's even a word) and maintaining data integrity between writes and updates.

Is there a recommendation of setting up a "transaction block" prior to begin of writes / updates and then commit or cancel transactions.

I am working with DF-EV2 implanted chipset. I want to be super mindful of error handling and managing data integrity so that I don't end up w/ bricked implanted chipset.

thanks
