Stream mode

In Stream mode, data from yaw, pitch and roll measurement are stored in the FIFO. A

watermark interrupt can be enabled and set as in the FIFO mode.The FIFO continues filling

until it is full (32 slots of 16-bit data for yaw, pitch and roll). When full, the FIFO discards the

older data as the new data arrives. Programmable watermark level events can be enabled to

generate dedicated interrupts on the DRDY/INT2 pin (configured through CTRL_REG3

(22h).

Stream mode is represented in Figure 9: Stream mode.
