MA702 unused registers?

Motor Drivers/Sensors

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?

I tended to just overwriting some undocumented registers. Is this a good idea :face_with_raised_eyebrow: ?

Hello pbuerckstuemmer,

It’s recommended to only use the registers documented in the datasheet. Depending on your use case, some of these might have no effect on the sensor behaviour. For example, if you are not using the ABZ outputs, you can use registers 4 and 5.

Kind regards,

Carmine

Hi Carmine,

thanks for your response. Good idea, I will probably do so. Won’t it be possible to find something out about the undocumented registers? There are probably some spare ones left. In total I’d like to store 4 bytes if possible.

Best regards
