I would like to cut the enable pin which takes a positive input and somehow use a switched negative output from a 3 mode driver.

Are you saying that you need an interface circuit to control the +enable pin by using the negative voltage from something else. What is the -voltage? Do they share a common ground?

....my posts must be read first before they appear, is there a way to expedite this?
It really slows down the process of figuring out a solution here lol.

I'm afraid not. This procedure was introduced by the Admin to stop spammers who had plagued this site (and many others). After two postings by a new member, all further postings are not vetted.

It should not cause delay because I visit this site at least twice a day, and most days up to four times a day.

You have deleted your original post, without bothering to answer Ken's question.
So can I assume your lack of patience and common courtesy means you are leaving us?
