I’m using the MA702 in an assembly unit and like to store several bytes (2-4) of calibration data temporarily within the MA702’s non-volatile memory. I noticed that there are registers 0x00 to 0x1f existent, but not all of them are mentioned in the datasheet. I wonder if we could (mis)use some of them to store the calibration data of our assembly unit. The behaviour of the unit should not change of course. Are there any of the registers unused?
