In fact, I load my program inside the MCU and i check the global application board consumption. (16mA @ 4MHz). After i force reset of MCU (to apply GND to reset Pin #1).

I think&nbsp;that the reset allow to "bypass consumption" of my MCU (because it don't run).&nbsp;A&nbsp;force reset manually could be provide a short circuit?</DIV><DIV>&nbsp;</DIV><DIV>In other word,&nbsp;i have my global consumption @ 4MHz = 16mA.
