Can you be aware but not conscious? According to Buddhist teaching (of any school) is it possible to be aware but not conscious? 

I'm reading the book Seeing that Frees at the moment and Rob Burbea hints that although in the book he is going to use consciousness and awareness interchangeably, there is a sense that they are not the same. I'm hoping that answers to this question might help me dig into this a bit more.
In descriptions of the five skandhas the fifth, Vijñāna, is described/translated as "consciousness" and "awareness": as if they're interchangeable.

But maybe there are other types of awareness. Ibid. says,


  This type of awareness appears to be more refined and introspective than that associated with the aggregate of perception (saññā) which the Buddha describes in the same discourse as follows [etc.]


And,


  Similarly, in the traditionally venerated 5th-century CE commentary, the Visuddhimagga, there is an extended analogy about a child, an adult villager and an expert "money-changer" seeing a heap of coins; in this analogy, the child's experience is likened to perception, the villager's experience to consciousness, and the money-changer's experience to true understanding (paňňā).[15] Thus, in this context, "consciousness" denotes more than the irreducible subjective experience of sense data suggested in the discourses of "the All" (see prior section); here, "consciousness" additionally entails a depth of awareness reflecting a degree of memory and recognition.


So maybe "awareness" is also used for sense-impressions (e.g. visual sight), which "consciousness" then reifies into a chariot, and/or "consciousness" is also used in the sense of "wisdom" (one word for which is 'higher consciousness')



I don't know about Buddhist teaching but it's reminding me of one time when my Tai Chi master pretended to attack me and I moved to block without thinking about it: so my action was aware (of what I saw) but unconscious.

Similarly when driving a car: when I was a student driver I had to consciously think about everything ... changing gear, other cars, road signs, stationary objects, indicators, the driving instructor, etc.  Now that I have more-or-less mastered driving it's sufficient to be aware of what I see around me, and to some extent being less conscious implies greater capacity for awareness.

Maybe I developed neural circuitry to handle the sense-input-signals from driving...
