One other thing that we discussed briefly.

The B0 or B1 bytes store only the bottom or top byte of the word so the maxium value in either would be 256 so we get 256 seeds if we use the odd number addition. Good for one different random cycle each night for 256 nights.

If I read and write BOTH B0 and B1 to eeprom addresses 00 and 01 then, using the odd number addition. I could get up to 65535 seeds correct?

Or, as you say, enough for 179 years of a different random combination each night? More than anyone could keep track of even if they wanted to.

Right or wrong?
