... Motion Detection Motion Detection (MD) mode is intended to be used to save system level power consumption. In this mode, the SCA3060 activates an interrupt via the INT-pin when motion is detected. Sensitivity levels can be configured via the SPI defined using sensitivity directions with AND / OR / mux logic. Once the interrupt has happened, the detected direction can be read out from the corresponding status register ...

... Ring Buffer 2.4.1 Description The SCA3060's Ring Buffer is a 192 acceleration data samples long (for example 64 samples of 11 bit three axis data) internal memory to relax real-time operation requirements of the host processor. The following parameters are configurable: 1. Each measurement axis can be individually disabled. If measurement data from e.g. Y-axis is not needed, available memory can be used for X- and Z-axis data ...

... Usage The Motion Detector will generate an interrupt to INT-pin when the corresponding function is enabled and the interrupt condition is met. The SCA3060's ring buffer will generate an interrupt when interrupt functionality has been enabled. Setting BUF_F_EN bit in INT_MASK register "1" results in interrupt when the register is 75% full. Setting BUF_H_EN bit in INT_MASK register "1" ...

... Communication between the SCA3060 sensor and master controller is based on serial data transfer and a dedicated interrupt line (INT-pin). Two different serial interfaces are available for the SCA3060 sensor: SPI and I enabled by pre-programming at the factory. The SCA3060 acts as a slave on both the SPI and I bus. 4.1 SPI Interface SPI bus is a full duplex synchronous 4-wire serial interface ...

... 2-wire serial interface. It consists of one master device and one or more slave devices. The master is defined as a micro controller providing the serial clock (SCL), and the slave as any integrated circuit receiving the SCL clock from the master. The SCA3060 sensor always operates as a slave device in master-slave operation mode. When using an SPI addressing is used (slaves have dedicated CSB signals), the I addressing (slave devices have dedicated bit patterns as addresses) ...
