8.12 Hall Element Direct Read Registers (16h to 29h)
Each hall element C1..C5 can be read independently, after each interrupt (data ready).
One hall element value consists of two 12-bit signed-registers: Cx_neg and Cx_pos. For each conversion cycle (i.e. after a readout or Y_res in
idle mode, or at each time-based conversion cycle in Low Power mode), each hall element is read twice: With normal spin (result Cx_pos) and
then with inverted spin (result Cx_neg) in order to remove any hall voltage offset from the hall elements.
The formula to read any hall element Cx:
Cx = (Cx_pos  Cx_neg) / 2
(EQ 1)
Where:
Cx_pos = (Cx_pos[11:8] << 8) | Cx_pos[7:0]
Cx_neg = (Cx_neg[11:8] << 8) | Cx_neg[7:0]
