Table 448. SLV0_CONFIG register description

SHUB_ODR_[1:0]

Rate at which the master communicates. Default value: 00

(00: 104 Hz (or at the maximum ODR between the accelerometer and gyroscope if it is less than

104 Hz);

01: 52 Hz (or at the maximum ODR between the accelerometer and gyroscope if it is less than

52 Hz);

26 Hz);

11: 12.5 Hz (or at the maximum ODR between the accelerometer and gyroscope if it is less than

12.5 Hz)

BATCH_EXT_SENS_0_EN Enables FIFO data batching of first slave. Default value: 0

Slave0_numop[2:0]
