If a not-latched interrupt is generated, the device waits in the normal mode till the interrupt
condition disappears. The minimum duration of interrupt activation is 330µs. If no interrupt is
generated, the sensor IC goes to sleep mode for a defined time (wake_up_pause).
For more details on the wake-up functionality, please refer to chapter 7.3
3.1.5 Wake_up_pause
These bits (address 15h, bit 2 and 1) define the sleep phase duration between each automatic
wake-up.
Table 5: Settings of wake_up_pause
Note: The accuracy of the wake-up timer is about ±30%.
3.1.6 Shadow_dis
BMA150 provides the possibility to block the update of data MSB while LSB are read out. This
avoids a potential mixing of LSB and MSB of successive conversion cycles. When this bit
(address 15h, bit 3) is at 1, the blocking procedure for MSB is not realized and MSB only
reading is possible.
