- *   The turn-on time to transition to another operating mode is calculated as:

- *   || 12-bit mode (high resolution) to 10-bit mode (normal): 1/ODR

- *   || 8-bit mode (low power) to 12-bit mode (high resolution): 7/ODR
- *   (Where ODR is the Output Data Rate - see lis3dh_dataRate_t for values)
