I2C_DISABLE Disable I²C interface. Default value 0. (0: I²C enable; 1: I²C disable)
LP
Low-power mode configuration. Default value: 0
If this bit is ‘1’, the DO[2:0] is set to 0.625 Hz and the system performs, for each
channel, the minimum number of averages. Once the bit is set to ‘0’, the magnetic
data rate is configured by the DO bits in the CTRL_REG1_M (20h) register.
SIM
SPI Serial Interface mode selection. Default value: 0
(0: SPI only write operations enabled; 1: SPI read and write operations enable).
