INTERNAL_FREQ_FINE (63h)

Internal frequency register (r)

FREQ_FINE[7:0]

Difference in percentage of the effective ODR (and timestamp rate) with respect to the typical. Step: 0.15%.

8-bit format, 2's complement.

The formula below can be used to calculate a better estimation of the actual ODR:

ODR_Actual = (6667 + ((0.0015 * INTERNAL_FREQ_FINE) * 6667)) / ODR_Coeff

The Selected_ODR parameter has to be derived from the ODR_XL selection (Table 50. Accelerometer ODR

selection) in order to estimate the accelerometer ODR and from the ODR_G selection (Table 53. Gyroscope ODR

configuration setting) in order to estimate the gyroscope ODR.
