Calibration with fuse

Hi All,

I am working on LRADC of MCIMX286CVM4B. I have to calculate the maximum and minimum error of ADC.  It has 12 bit of resolution and an absolute accuracy of 1.3% limited primarily by the accuracy of the bandgap voltage reference but if the bandgap voltage reference is calibrated with the fuses, the LRADC absolute accuracy might be improved to better than 0.5%.

Can anyone explain me the procedure (or can give reference link) to calibrate voltage reference with fuse in order to improve accuracy?

Thanks.
