GHIDRA Disassembly, SH7058 sh2a finding maps XREFS

DENSO SH7058 SH2A big endien.
3d structures e0780 was corrected too DW_3Dstruc_000780, from mistakenly calling it TPS_%.
Some maps were not 'XREF' from the initial analyze. This video is addressing one of the instances.
This is my first project in Ghidra, and I have no background in EE feel free to ad any information or corrections in the comments, don't look to my videos as the "right" way too do it.

The datatype was "db *" which is a pointer to a "db" (which itself is basically a byte). At one point, I saw "db * * * * *", which I think happens when you already had a datatype there and hit the "p" key to make a pointer. Hitting it again adds a layer of indirection.. One way to create a structure (perhaps you did that) is to define some data in memory, select the data, then right click -> Data -> create structure from selection. That will use the selected data and create a structure with those data elements (and replace them in the memory with an instance of the new structure).
