The recommended power-on sequence is to first apply VDD, then VLOGIC, and finally enable the accelerometer by setting the EN pin high.
The interrupt pins can be configured using the INT1_CFG and INT2_CFG registers. The interrupts can be triggered by events such as new data availability, FIFO overflow, or threshold exceedance.
The FIFO buffer is used to store acceleration data temporarily, allowing the microcontroller to read data at a slower rate than the accelerometer's sampling rate, reducing the load on the microcontroller.
The BMA250E has an internal self-test feature that can be used for calibration. The self-test feature applies a known acceleration to the sensor, allowing the user to determine the sensor's sensitivity and offset.
The maximum sampling rate of the BMA250E is 1.56 kHz, but it can be adjusted to lower rates such as 125 Hz, 250 Hz, or 500 Hz depending on the application's requirements.
