AHPM[1:0] High-pass filter mode selection for acceleration data. Default value: 00

Refer to Table 53

AFDS Filtered acceleration data selection. Default value: 0

(0: internal filter bypassed; 1: data from internal filter sent to output register and FIFO)

T_ONLY Temperature sensor only mode. Default value: 0

If this bit is set to ‘1’, the temperature sensor is on while the magnetic sensor is off.
