aw god this isn't funny any more! (actually... it is). there's a
store-with-update that's separate from load-with-update. so there are
* LD Mode will activate Issue, GoRead1, GoAddr then GoWrite1
* LD-UPDATE Mode will *additionally* activate GoWrite2.
* ST Mode will activate Issue, GoRead1, GoRead2, GoAddr then GoStore.
ST-UPDATE Mode will *additionally* activate GoWrite2.
i might be able to recover the current diagram without rewriting it.
