FIFO reading procedure

The data stored in FIFO are accessible from dedicated registers (FIFO_DATA_OUT_L

(3Eh) and FIFO_DATA_OUT_H (3Fh)) and each FIFO sample is composed of 16 bits.

All FIFO status registers (FIFO_STATUS1 (3Ah), FIFO_STATUS2 (3Bh), FIFO_STATUS3

(3Ch), FIFO_STATUS4 (3Dh)) can be read at the start of a reading operation, minimizing

the intervention of the application processor.

Saving data in the FIFO buffer is organized in four FIFO data sets consisting of 6 bytes

each:

The 1st FIFO data set is reserved for gyroscope data;

The 2nd FIFO data set is reserved for accelerometer data;

The 3rd FIFO data set is reserved for the external sensor data stored in the registers from

SENSORHUB1_REG (2Eh) to SENSORHUB6_REG (33h);

The 4th FIFO data set can be alternately associated to the external sensor data stored in the

registers from SENSORHUB7_REG (34h) to SENSORHUB12_REG (39h), to the step

counter and timestamp info, or to the temperature sensor data.
