Long after the fact but I finally looked it up:

Eatsleepboost is correct in that MA allows one non-continuous monitor to be not-ready.

However, he mistakenly identifies the cat-related monitors as continuous.

The following are non-continuous monitors for gasoline engines:

Catalyst (CAT)
Heated Catalyst
Evaporative (EVAP) System
Secondary Air System
Oxygen (O2) Sensor
Oxygen Sensor Heater
EGR (Exhaust Gas Recirculation) and/or VVT System
