 The CPI range is 50-16000, in increments of 50. Defaults to 2000 CPI.
 
 Both PMW 3360 and PMW 3389 are SPI driven optical sensors, that use a built in IR LED for surface tracking.
+If you have different CS wiring on each half you can use `PMW33XX_CS_PIN_RIGHT` or `PMW33XX_CS_PINS_RIGHT` in combination with `PMW33XX_CS_PIN` or `PMW33XX_CS_PINS` to configure both sides independently. If `_RIGHT` values aren't provided, they default to be the same as the left ones.
