according to datasheet:

Register(0x4B)

Data sampling (32 kHz) clock frequency adjust. This register is used to calibrate the sample frequency of the device to achieve high precision on the data rate as defined in Register 0x12. Adjusts the
sample master 32 kHz clock by 0.6 kHz per LSB. For a 100 Hz sample
rate as defined in Register 0x12, 1 LSB of Register 0x4B, Bits[5:0], is
1.9 Hz. Note that a larger value produces

 

If sample rate set 21Hz,what hz of 1LSB of register 0x4B?

 

600/(32000/21)=0.393 Hz ? Is this correct ?
