Issuing a generic memory barrier is workable, but it kills performance, as all variables will be reloaded again. Performance does matter when working on microcontrollers.
Could I ask for a reality check here. That sounds more like a cache flush, while a membar only ensures that any reordered reads and writes are disentangled: I'd not expect it to invalidate registers.
