bma456 has a tilt-on-wrist detection interrupt. When ever the device is rotated more than a minimum of 12 degrees to gravity, an interrupt interrupt is generated. In the data sheet, it says "The Tilt on Wrist Interrupt is detected with one accelerometer axis. Therefore, you should make sure that the active axis is mapped to the portrait up direction of the device by using the axis remapping functionality of BMA456." How does this work?
Also the data sheet specifies that the device should be lifted to a comfortable position first then rotated. Would the accelerometer detect a tilting gesture while the device is lifted and rotated at the same time?
