read failed: Illegal data address

It's much better to use bit functions for setting bits:

Code:

function setbit(value, nr)
  return bit.bor(value, bit.lshift(1, nr))
end

value = 0

value = setbit(value, 0)
value = setbit(value, 1)
value = setbit(value, 9)

log(value) -- result: 515

The only thing I don't understand is why you have 1-byte value and bool values setting the same bits. How many writable bits are there?
