I am planning to use atmega324P device in my application.
I need an edge trigger interrupt to wake up this device from the sleep mode & perform necessary action and again enter sleep mode.
The table 7-1.(page no. 43 of full data sheet) in the device data sheet provides sleep modes and wake up sources. The note 3 specifies:
For INT0, only level interrupt.
1. Does that mean for INT1 and INT2 edge trigger interrupt is available?
2. In table 7-1, for each mode columns marked with 'X' means these functionalities will be available during sleep mode? Is this statement true?
3. How can we estimate the consumption of device in power save, power down mode at 4 MHz clock frequency?
Thanks in Advance.
