The invensense ICM-20608-G power modes in the datasheet are well enumerated, but it is unclear how to enter those modes. There does not seem to be a direct value that can be written to a single register to enter a given mode.
What is the sequence of register to writes to enter
6-Axis Low-Noise Mode?
How can I confirm that I've entered that mode?
What is the default power mode on reset?
