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 CTRL_REG3_G (22h)) in order to be raised when

the FIFO is filled to the level specified in the WTM 4:0 bits of FIFO_CTRL_REG_G (2Eh).

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,

FIFO_CTRL_REG_G (2Eh) must be written back to Bypass mode.

FIFO mode is represented in Figure 7.
