Well the accelerometer still needs to consume energy when configured in irq. You just save the efm the need to wake up for polling data. So the EFM still consumes 1.2µ because it is in EM2 and then you need to add the accelerometer consumption which depends on the ODR.
The SDK is low conso. We did everything we could so that it would go into the lowest energy mode required by your application.
