Default values
Serial address
Byte addresses
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.
Default value
Serial address
Byte address
The value in this register, in combination with the DEV_ID register, serves to identify the MIC3003 and its revision number to
software.
This register is read-only.
