What do you use the instruction for?
If you use it as an assertion then probably it should exit the
simulation and write diagnostics.

How does the break instruction depend on fuses?

Devices with small instruction set do not implement the BREAK
instruction, however this looks like a limitation of silicon, not a
feature. It would be useful if libraries could use this instruction in
assertions on any device (in simulator).
Is it useful to simulate the limitation? When/why?
