The poster there said, after I recommended changing from LOW to FALLING: "Wow. Nick you were right. Tried it with FALLING and it works like a charm. Thanks!" As you noted @Gerben, using LOW has its own problems. | |

I raised a ticket at Atmel and got this response: "Our design team has confirmed that “Note-3 mentioned under Table 10-1” is a datasheet bug. So you can use any type of interrupt (Rising edge/ Falling edge / Low level / Any logical change) to wake up from sleep mode. Sorry for the inconvenience caused." | |

@NickGammon I never got it to work on anything other than LOW trigger. The datasheet says in table 10.1, note 3; For INT1 and INT0, only level interrupt. The example on the page you link to also only uses LOW triggers.
