ROM limit to 24 bits - why?

[GaryMcD]

Is there a constraint that requires the limit to be 24 bits? I would like to use a rom with a 32 bit address. I have found that I can get around this by opening the .dig file and setting the value to 32 bits, but it will get set back to 24 if I ever use the GUI to change anything else on the rom.

= new Key.KeyBits("AddrBits", 2).setMax(24); // needs to have the same default value as INPUT_COUNT!!! see de.neemann.digital.gui.components.EditorFactory#DataFieldEditor

What do you want to store in a 4GByte ROM?

I admit - a 4Gbyte ROM is a bit excessive. With that said - it seems that all of the memory is limited to 24 address bits, even the RAM. I was working on simulating a RISC-V, 32bit CPU which has 32bits for addressing
