 |
|
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

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. |
