Hi everyone, we're using the BMI270 and are trying to save every uA we can.
The savings from Normal mode/Performance Mode to Low power mode are enormous (as per page 28 on the datasheet). To access Low power mode, it states that we have to enable PWR_CONF.adv_power_save.
Following on on page 29 (extract below) the language in the dot points confuse me. Is this implying that when adv_power_save=1 the new data is only in the FIFO registers and NOT in the standard registers?
We currently operate the gyroscope at 25Hz and are happy to poll it at a 25Hz interval without the need for FIFO. We'd rather not have to implement FIFO if it's not neccessary to keep the project moving along.
Much appreciated!

Hello SoWizard,
In low power mode, the register data will also be updated.
