Low Power Operation

[igor-swit]

What would be the right way to achieve low power operation? To put MCU to sleep until next interrupt?

I'm not sure if idle task is the right way to do it since there might be a race condition: interrupt happens right before sleep, ISR does its thing e.g. signaling something, but since MCU goes to sleep signal from ISR never gets processed, at least not until next interrupt?

I understand QuarkTS is hardware independent but this is kind of a big thing. I'm trying to figure out if QuarkTS is a way to go, so...
