It seems to work well, but startup is a problem.  It starts out on input
1 but if you stop the program it can get lost.  I need to add a reset
circuit.  Any suggestions?

Require it to be clocked every so often, reset if it is held high for a
certain length of time.

Alternatively, it may be possible to drop the voltage to zero - but that
would require a firware change... anyway, I'll look into it out of
interest.

Cheers,

Ben.
