... General Description 1.1 Introduction CMA3000-D0X is a three axis accelerometer family targeted for high volume products requiring small size, low price and low power consumption. It consists of a 3D-MEMS sensing element and a signal conditioning ASIC in a wafer level package. Block diagram of CMA3000-D0X is shown in Figure 1 below. ...

... Motion Detection Motion Detection (MD) mode is intended to be used to save system level power consumption. In this mode, CMA3000-D0X activates the interrupt via the INT-pin when motion is detected. Motion sensitivity level can be configured via the SPI or I detected can be user defined. Once the interrupt has happened, the detected direction can be read out from the corresponding status register ...

... Measurement Mode 2.3.1 Description The CMA3000-D0X is set to a measurement mode by writing MODE[2:0] = 0XXb to CTRL register. Data will be reliable in the output registers after the product specific turn-on time. Default sample rate is 400 Hz (MODE[2:0] = 010b). Other data rates are 100 Hz (MODE[2:0] = 001b) and 40 Hz (MODE[2:0] = 011b). ...
