| `PMW33XX_CS_PIN` | (Required) Sets the Cable Select pin connected to the sensor. | _not defined_ |
| `PMW33XX_CS_PINS` | (Alternative) Sets the Cable Select pins connected to multiple sensors. | _not defined_ |
| `PMW33XX_CPI` | (Optional) Sets counts per inch sensitivity of the sensor. | _varies_ |
| `PMW33XX_CLOCK_SPEED` | (Optional) Sets the clock speed that the sensor runs at. | `2000000` |
| `PMW33XX_SPI_DIVISOR` | (Optional) Sets the SPI Divisor used for SPI communication. | _varies_ |
| `PMW33XX_LIFTOFF_DISTANCE` | (Optional) Sets the lift off distance at run time | `0x02` |
| `ROTATIONAL_TRANSFORM_ANGLE` | (Optional) Allows for the sensor data to be rotated +/- 30 degrees directly in the sensor. | `0` |
| `ROTATIONAL_TRANSFORM_ANGLE` | (Optional) Allows for the sensor data to be rotated +/- 127 degrees directly in the sensor. | `0` |
To use multiple sensors, instead of setting `PMW33XX_CS_PIN` you need to set `PMW33XX_CS_PINS` and also handle and merge the read from this sensor in user code.
Note that different (per sensor) values of CPI, speed liftoff, rotational angle or flipping of X/Y is not currently supported.
