IIS2DLPC - BDU - Temperature data

Hi,

Do enabling BDU also protect temperature data registers from getting refreshed while reading the data? Or is it just for accelerometer data registers? 

BR,

KJ

Hi ​@Federica Bossi ,

Thank you for your quick response!

It makes sense that it is intended for accelerometer output registers. However, I would like to know whether it also guarantee coherent reads of temperature output registers atleast to some extent.

Best regards,
