I'd like to hear other users'/developers' opinions about *which*
direction to make this consistent into. Should we:
[ ] Use 'x' consistently for all efuse bits that are not defined for
a particular part, or
[ ] always use 'i' for all bit positions of the entire efuse byte?
(I think lfuse and hfuse are always a full byte. Otherwise, this
question would extend to them as well.)
