 normal mode of operation

I was talking about, normal mode of operation, not low-power one.

Some sensors only provide way to set output data rate, even when it samples at 8kHz, like 6DoF sensors.

Maybe we can keep simpler concept at this time? {frequency: Hz} would be the rate at which data is delivered = ODR in HW sensor terms. We can spec it as 'reporting' frequency.
