Hi team,


I would like to ask about the bandgap reference voltage calibration.

i.MX28 reference manual(MCIMX28RM Rev.2) says as below.(Table 38-1)

"But if the bandgap reference is calibrated using the fuses, then …"

Could you show me what the 'calibration with fuses' is?

And could you show me the procedure of the calibrate with fuses?
