10.3 Register 18 – FIFO Enable
10.4 Registers 19 – AUX (Accel) VDDIO
Type: Read/Write
Description:
This register determines what data goes into the IMU-3000 FIFO, which is a 512 byte First-In-First-
Out buffer (see register 60). Sensor data is automatically placed into the FIFO after each ADC
sampling period is complete. The ADC sample rate is controlled by register 21.
The order at which the data is put into the FIFO is from MSB to LSB, which means that it will match
the order shown in the parameter detail below. Two bytes are used for each reading. For example,
if Gyro X, Gyro Y, Gyro Z, and FIFO_FOOTER are configured to go into the FIFO, then each sample
period the following 8 bytes would be inserted into the FIFO, as shown below:
