Description

i think the ROM entry in the library reference could use an update. first, the guide says that two ROMS will always have the same values; i'm pretty sure this is not true anymore. also, it says each value can be up to 32-bit; now, it can go up to 64-bit. also, it doesn't have an image of the new look of the ROM. and, to my knowledge, the ROM doesn't include a select pin anymore. i think it would be less confusing if this was fixed, mainly when beginners are confused why there's no sel pin. either than that, to my knowledge, the library reference is fine. thanks for reading (:

Research direction
The issue describes outdated information in the ROM entry of the library reference. To fix it, locate the ROM documentation file in the repository (likely under src/main/resources/doc or similar). Update the text to reflect that ROM values can be up to 64 bit, remove claim about two ROMs always having same values, add a new image of the current ROM appearance, and remove mention of a select pin. Verify the changes match the current ROM component behavior in the source code.
