3.3.1 Step 1: Convert Frequency Compensation Codes to Error Percentages

For each frequency compensation register, recover the error percentage the register encodes using the pre-calibration Gain 2 code Coriginal:

Equation 23. ErrorFS1=FREQ_SLP1original0.01×(Coriginal-18687.13)

For the error associated with FREQ_SLP2, the equation becomes:

Equation 24. ErrorFS2=FREQ_SLP2original0.01×(Coriginal+FREQ_SLP1original-18687.13)
