What is the true definition of coercion by a attorney for a plea?

It is what the court ( judge) decides it is if there is a challenge.

First is it a defense attorney trying to get his client to take a plea or is it the DA.

The DA of course can lie, misrepresent what evidence they may have and do many things to try and get them to settle.

Hello k:

If he holds a gun up to your head and makes you sign... Short of that, there's NO coercion.
