Hi - I'm looking at the datasheet for an ATMEGA168PV. I plan on using it in power-save mode frequently. I would ideally like it to be able to wake up both from a change on INT0 and an interrupt on Timer2.
In table 10-1 in the datasheet (page 40), it says it says "For INT1 and INT0, only level interrupt." can wake up the device out of power save.
Table 13-2 in the datasheet (page 69) lists four options for INT0 interrupts: low level, logic change, falling edge, and rising edge.
So it seems like it will definitely not wake up using the last two options. I think it definitely will wake up using the low level option. But what about the logic change option? That is the option that I am most interested in using.
