74 - 87 = 4Ah - 57h
These registers hold the slope and offset coefficients used to calibrate the MIC3003’s ADC results in internal calibration mode.
Note that the temperature offset is also used in external calibration mode; but this can be disabled in OEMCFG5 (or by setting
the offset coefficient to zero).
These registers are non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for
access to these registers.
