Meaning of this data representation in datasheet

Hi,
I need to use a sensor able to communicate by SPI but I have some trouble to understand the meaning of the data prensented between parenthesis and separate by a colon…

Example, here page 12 we can see “Angle (15:0)” or “Angle (15:4)”

What does it mean ?

Thank you!

It indicates the bits that are actually containing data. So if you get a 16 bit value, only bits 15 … 4 contain relevant data and bits 3 … 0 can be ignored.

So you can shift 4 bits to the right to get the value.

Thank you :grinning:
