Hello,
Atmega88PA and Bascom 2.0.8.1

If i use Config Powermode= idle, my programm works fine, it wake up with INT0, and the Timer1 works (consuming 1mA)

If i use Config Powermode= Powerdown, my programm wake up with INT0, but the Timer1 NOT run (consuming 0.04mA)

I need save much power as possible, how use sucessfull the Powerdown?

Thank for help
Best regards
P_Santos

Surprisingly the data sheet shares the same opinion, in particular that timers won't run while in Powerdown.

Never - in case the timer needs to run.

Timers and external Interrupts will run however in Powersave, additionally there's a register called PRR, which can turn off integrated units which are not required within Powersave state.

Your starting post did not sound as if this would be an option.
