Well there are a few things that could be going wrong.
1. The front cat (right under the manifold) might be bad. This can be diagnosed by check the front and rear 02 sensors the see if they are switching at the same rate (ie the cat is bad).
2. There might be a PCM update for this code, but if left too long you might need to replace both the front cat and have the pcm updated.
So my sudgestion is to see a Mazda dealer for this code.
