documentation for dlog output

[Michael Mitchell]

At the end of dlog trace, we get the following.  

These seem like basic assembly instructions with addresses but I have no idea what any of it means, and I can't find any documentation for it.  Can someone take the time to go through the significance of each one by one, and that way at least if anyone else does a google search this email chain might show up.

That is a register dump. It is showing you a list of CPU registers
and the value in each register.
