Hi,

I am unable to find out whether an i2c write can be used to wakeup the Attiny when its used as a slave. Can anybody please help?

Thanks and Regards,

You missed:

26.3.7 Sleep Mode Operation The bus state logic and slave continue to operate in all Sleep modes, including Power-Down Sleep mod****e. If a slave device is in Sleep mode and a Start condition is detected, clock stretching is active during the wake-up period until the system clock is available. The master will stop operation in all Sleep modes.
