The recommended power-on sequence is to apply VDDIO before VDD. This ensures that the internal voltage regulators are properly powered up.
To configure the LIS3DHHTR for low-power mode, set the LPEN bit in the CTRL_REG1 register to 1. This reduces the current consumption to approximately 10 μA.
The self-test feature in the LIS3DHHTR is used to verify the integrity of the sensor's mechanical structure and the analog-to-digital converter (ADC). It does not test the entire signal chain, but rather the sensor's ability to detect a known stimulus.
The LIS3DHHTR outputs 16-bit, two's complement data in the range of -32768 to 32767. The output data represents the acceleration in mg (milli-g) units, with a sensitivity of 0.061 mg/LSB.
The maximum frequency of the data output from the LIS3DHHTR is 1.6 kHz, which is the maximum ODR (Output Data Rate) setting.
