On the combination ROM/Cache module I presume that the majority of pins are active. On the Cache Only module, I presume that fewer pins are active.
If you can identify which pins are for the ROM function, you can disable them. That would leave you with a ROM/Cache module on which the ROM is disabled and the Cache is active. Are the pinouts in a developer note somewhere?
