LPS22DF static addresses: 0x6B/0x6A or 0x5C/0x5D

We have a STEVAL-MKI224V1 kit, which should be equipped with a LPS22DF. I have tried to use the static (I2C) address of the sensor, and after much time, I discovered it is (depending on the state of SDO) 0x5C/0x5D, and not 0x6B/0x6A, as stated in the...
