3.2.2 FIFO mode
In FIFO mode, data from the yaw, pitch, and roll channels are stored in the FIFO. A
watermark interrupt can be enabled (I2_WMK bit in CTRL_REG3), which is triggered when
the FIFO is filled to the level specified in the WTM 4:0 bits of FIFO_CTRL_REG. The FIFO
continues filling until it is full (32 slots of 16-bit data for yaw, pitch, and roll). When full, the
FIFO stops collecting data from the input channels. To restart data collection, it is necessary
to write FIFO_CTRL_REG back to bypass mode.
FIFO mode is represented in Figure 8.

3.2.3 Stream mode
In stream mode, data from yaw, pitch, and roll measurements are stored in the FIFO. A
watermark interrupt can be enabled and set as in FIFO mode. The FIFO continues filling
until full (32 slots of 16-bit data for yaw, pitch, and roll). When full, the FIFO discards the
