When the corresponding criterion becomes valid, the interrupt pin is triggered to a high level. As a consequence, no write sequence should occur when microprocessor is triggered by interrupt or the interrupt should be deactivated on the microprocessor side when write sequences are operated. As a consequence all thresholds are scaled with range selection section 3. Timings used for any motion interrupt and alert detection are proportional to bandwidth settings section 3. It can not be turned on simultaneously with alert. When this bit is at 0, interrupts are set and reset directly by SMB according to programmable criteria sections 3.

Freely programmable, fully digital sensor! Very small dimensions: 3 mm x 3 mm x 0. Specifically designed for low-power applications in consumer electronics products With the new SMB acceleration sensor, Bosch Sensortec is adding an extremely small digital sensor with a customized setting function to its product line of triaxial sensors. The SMB is especially suitable for human machine interfaces HMI , free-fall detection, as well as mobile and ultra-low-power applications.
The sensor will be available as an engineering sample from January Bosch Sensortec plans to start series production in June By introducing the SMB, Bosch Sensortec is consistently expanding its product range towards miniaturized sensors. In comparison with the current generation, its size is reduced by 50 percent. Measuring only 3 mm x 3 mm x 0. The new sensor offers several special features, such as a programmable interrupt pin.
Interrupt logic for various application possibilities The sensor supports customer products in evaluating movement profiles and in releasing reactions via an interrupt line. The sensor logic can be configured with the help of a programmable interrupt pin to analyze high-g or low-g thresholds or to recognize gentle movements.

Page When the sensor IC goes from sleep to normal mode, it starts acceleration acquisition and performs interrupt verificatio section 3. The sensor IC automatically switches back from normal to sleep mode aga f ulfilment of programmed interrupt criteria has been detected If this bit address 15h, bit interrupts are latched.
