FIFO mode
In FIFO mode, data from the yaw, pitch and roll channels is stored in the FIFO. A watermark
interrupt can be enabled (I2_WMK bit in the CTRL_REG3_G register) in order to be raised
when the FIFO is filled to the level specified in the WTM 4:0 bits of the FIFO_CTRL_REG_G
register. 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, the FIFO_CTRL_REG_G register must be written back to Bypass mode.
FIFO mode is represented in Figure 7: FIFO mode.
