Description

For 0x10 (./i/10_fieldwire.gif)
0x10 -> 0001 0000 # cool
split to field and wire of 00010 and 000, # good so far
but the label under field is "1" instead of "2"
and the label under wire is "2" instead of "0"

For 0x18 (./i/18_fieldwire.gif)
0x18 -> 0001 1000 # cool
field is 00011 and wire is 000 # yup
field's label is "3" which is correct, but
wire's label is "2" again, instead of "0"

I'm not sure how that effects the explanations of what the fields mean.
