RAM dump format for Swiss Micros DM41s?

[KF6GPE]

Hi! Long time user, intermittent collector, intermittent visitor to the forums over the years. Couldn't resist getting a Swiss Micros DM41L recently (very happy!). Thanks to all for participating in the other DM41 discussions; it both helped me confirm my decision to purchase and get the serial communications working quickly.

Was wondering if anyone knew a few things about the RAM dump format off of the serial port. It's obvious that the first block are the memory contents as registers, each separated by spaces --- but why start at location 0x8? And why are some, but not all, processor registers dumped? (I don't see D, E, and F, for example).

Just curious.
