I'm unclear about the the different types of interrupts generated by LIS2DE12 and similar devices.
In CTRL_REG3 (22h), the following interrupts can be enabled:
I understand what CLICK, WTM, and OVERRUN do, but I'm not completely sure about IA1, IA2, and ZYXDA. It appears that IA2 can be used for wake up interrupts defined by a threshold and duration, is that the same for IA1? What about ZYXDA?
I looked for app notes or other documentation that explain these interrupts, but I haven't found much so far.
Can someone point me to the appropriate document?
