List of Registers
5.1.4
0x0110 (read only) – Temperature Sensor
During every measurement cycle the internal temperature is measured sequentially with the magnetic
values. The temperature value is used for internal compensation of magnetic sensor offsets and
sensitivity drifts and is also available in output register 0x0110.
Bit

Description
D15 (MSB)
–
D0 (LSB)
T
“Temperature”
Output value of the internal temperature sensor. 16 bit signed
integer value in
two’s complement representation.
Conversion (typical): T [°C] = T [LSB] / 200 [LSB/°C] + 25°C
0x0110 Bits
5.1.5
0x0111 (read only) – Bi
0
Magnetic Field
Depending on the table selection (Bits TableSelect in register 0x000B) the Bi
0
output register can hold
different magnetic field components. For an overview of the Bi
