1. Mode 3 is enabled when the OIS_EN_SPI2 bit in the CTRL1_OIS (70h) register is set to 1. Mode 4 is enabled when both the OIS_EN_SPI2 bit and
the Mode4_EN bit in the CTRL1_OIS (70h) register are set to 1.
2. INT1 must be set to '0' or left unconnected during power-on if the I²C/SPI interfaces are used.
Internal pull-up value is from 30 kΩ to 50 kΩ, depending on VDDIO.
Note: The procedure to enable the pull-up on pins 2 and 3 is as follows:
1. From the primary I²C/I³C/SPI interface: write 40h in register at address 01h (enable access to the sensor hub registers)
2. From the primary I²C/I³C/SPI interface: write 08h in register at address 14h (enable the pull-up on pins 2 and 3)
3. From the primary I²C/I³C/SPI interface: write 00h in register at address 01h (disable access to the sensor hub registers)
