INT1 and INT2: There are two optional interrupt output pins on this sensor, which can be configured to change their state when one or more 'events' occur.

Please note that SPI mode is not actively support and the SPI pins are not all 5V safe and level shifted, so care will be required when using it! The default of logic high sets the board up for I2C, and manually setting this pin low and resetting will cause the device to enter SPI mode.

CS: This dual purpose pin can be used as the chip select line in SPI mode, but also determines whether the board will boot up into I2C or SPI mode.

If you set this pin high (to 3.3V), and reset, the I2C address will be updated to 0x1D. By default this pin is pulled down, meaning it has a value of 0 at startup, which will results in an I2C address of 0x53.

SDO/ALT ADDR - This pin can be used as MISO in SPI mode, but is more commonly used as an optional bit in the I2C bus address.
