Reference Coefficient B
Reference calibration coefficient B LSB. Use with coefficients A and C and the measured reference value to obtain
the compensated reference measurement. This result may be compared to limits given in the “Electrical
Specifications” table beginning on page 7 to check that the reference is within limits. The register contents may be
read by the user but not written to.
