I think you might be confused on what an IS is. Having rom is not an IS. Designing OP codes that need to be decoded, along with where you IMM will go and what registers to use is an IS. Not your ROM.

I've seen times were the ROM has registers in its place. It isn't usable as registers/RAM but is much better as an easy way to write lines. One can stay in one spot and program them machine and change the programs easily without moving from the I/O.
