Figure SCU (Sensor Control Unit)-76 Data Normalization (Example)
When the data is not passed through the MATH_PROC, the offset and writing length can be selected for a
maximum of 16 Bytes of data that was captured by the SPI, I2C, LPADC, or HPADC.
The data ultimately written to the FIFO, when not passed through the MATH_PROC, is written in the readout
order from the sensor.
When passed through the MATH_PROC, you can select from 16 bits or 8 bits for each element (bits per axis).
(OUTPUT_8BIT of Section 3.9.12.11.11.)
When 16 bits is selected for each element, writing is performed in the X,Y,Z order from the LSB side byte.
When 8 bits is selected for each element, the MSB side 8 bits of each X,Y, and Z are written in X,Y,Z order.
Figure SCU (Sensor Control Unit)-77 shows how the data is ultimately stacked in the FIFO.
