| 36 | * Platform data is used to setup the sensor chip. Meaning of the different | ||
| 37 | * chip features can be found from the data sheet. It is publicly available | ||
| 38 | * at www.st.com web pages. Currently the platform data is used | ||
| 39 | * only for the 8 bit device. The 8 bit device has two wake up / free fall | ||
| 40 | * detection units and click detection unit. There are plenty of ways to | ||
| 41 | * configure the chip which makes is quite hard to explain deeper meaning of | ||
| 42 | * the fields here. Behaviour of the detection blocks varies heavily depending | ||
| 43 | * on the configuration. For example, interrupt detection block can use high | ||
| 44 | * pass filtered data which makes it react to the changes in the acceleration. | ||
| 45 | * Irq_flags can be used to enable interrupt detection on the both edges. | ||
| 46 | * With proper chip configuration this produces interrupt when some trigger | ||
| 47 | * starts and when it goes away. | ||
