DMA should be able to have a direct connection to the HP port.

Current implementation is through a separate iconnect and it works. This commit undid the failing attempt:

Removing the iconnect and connecting directly compiles, simulates but the copied results are 0. This commit has the failing version.

My guess is that it has to do with addresses.

the iconnect uses RELATIVE removing the iconnect automatically goes to absolute. but changing to ABSOLUTE does not make it fail
so it is something else
