These questions were never answered in the last post for the IIS3DWBTR related to the I2C interface.

Questions for the IIS3DWBTR:

But as I mentioned in my other post and repeated here, I don't care about getting the data out at high sample rates. I'm just using the interrupts for thresholds and want to use this part because it has a higher bandwidth for detection.

In I2C mode for the IIS3DWB device the datasheet says it only support single axis mode because I2C is too slow to get the data. I want to use I2C mode to configure either wake up or activity thresholds for all 3 axis and then configure the interrupts to tell me those thresholds were exceeded. I don't need the data.

So the questions are In I2C mode:

  1. Are all the axes still active?
  2. Can I access all the registers in I2C mode to configure the thresholds for all axes of the device for the interrupts?
  3. Can I effectively get two thresholds for each axis if I use one set of thresholds for wake up configured on INT1 pin and another set of thresholds for activity configured on INT2 pin?
  4. What is the max rate of the I2C interface?
