I thought[*] 7 was the highest priority, and 0 the lowest (on a narrow
channel).  Wide devices have an even lower priority: 15 to 8.

So you have in decreasing order of priority:

    7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8

[*] I'm not 100% sure about the actual order, but I'm sure there was a
    discontinuity between narrow and wide devices, so only the above ordering
    makes sense, unless I'm missing something.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
