I tried that originally. The LED subsystem seems quite complex for something
as simple as turning on a bit in a register. I don't have a DB1200 to test
so I went the safe route and added a simple callback to toggle the LED bit in
the DB1200 FPGA.

I'll try to come up with something over the weekend and then resend the
whole series.

Thanks!
