 !> When using `SPLIT_POINTING_ENABLE` the `POINTING_DEVICE_MOTION_PIN` functionality is not supported and `POINTING_DEVICE_TASK_THROTTLE_MS` will default to `1`. Increasing this value will increase transport performance at the cost of possible mouse responsiveness.
 
+The `POINTING_DEVICE_CS_PIN`, `POINTING_DEVICE_SDIO_PIN`, and `POINTING_DEVICE_SCLK_PIN` provide a convenient way to define a single pin that can be used for an interchangeable sensor config.  This allows you to have a single config, without defining each device.  Each sensor allows for this to be overridden with their own defines. 
 
 !> Any pointing device with a lift/contact status can integrate inertial cursor feature into its driver, controlled by `POINTING_DEVICE_GESTURES_CURSOR_GLIDE_ENABLE`. e.g. PMW3360 can use Lift_Stat from Motion register. Note that `POINTING_DEVICE_MOTION_PIN` cannot be used with this feature; continuous polling of `get_report()` is needed to generate glide reports.
