Is there a current part of the SVD specification for working with fields defined in this way? I would like to be able to use something like enumeratedValues combined with a bitmask for ignoring irrelevant bits on reads, and not clobbering those bits on writes.
As a work-around, it's obviously possible to just split the field into separate field definitions, and document their relation. However, I would like to be able to define this using the type system in the generated code.
If this capability is not currently in the specification, would it be desirable/possible to add it in a future version?
I would be happy to contribute time/effort in design and development work.
In certain hardware descriptions, bit fields can be split across multiple ranges with significant bits in between.
An example I've recently come across: https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/stmicro/stmmac/dwmac1000.h#L275,
