It assumes everything is readable unless it's explicitly told otherwise
or the register map is overall write only (like a 7x9 one). You could
mark the registers as precious to cause it to only do explicit I/O
operations on them but that's not what you mean and won't be as good a
guarantee that nothing can trigger a read.
