What is the meaning of Output data rate of Bosch BMI270?

Question

what is the meaning of ODR (output data rate)

BMI270 says it has 1.6kHz for accelerometer ODR

does it mean internal registers update rate is 1.6kHz

or

1.6kHz/(16bit x 3) = 33Hz ? (here 3 is, 3 axis)

or

1.6KHz/ (16bit) = 100Hz? (per each 16bit register)

does it mean internal registers update rate is 1.6kHz

True. Think of it to be something like mesurement rate. It'll give you the updated data at a rate of 1.6kHz when you query through SPI or I²C.

\$\begingroup\$ so its the maximum sample rate the MCU can achieve? (ODR 1.6kHz = each accelerometer 16bit register update rate = maximum achievable sample rate for accelerometer data is 1.6kHz) correct me if this is wrong \$\endgroup\$

\$\begingroup\$ @oppo yes. Even if you query faster it will probably give you the last updated content. \$\endgroup\$
