Values in the tables that look like ```this``` are the names of sysfs attributes or values returned by said attributes.
[1]: When in COL-CAL mode, the color sensor does not respond to the keep-alive sent from the EV3 brick. As a result, the sensor will time out and reset after 1-2 seconds in COL-CAL mode. When using this mode, you should set the mode, do what you need to and change back to another mode within 1 second. Of course, LMS2012 does not appear to use this mode when "calibrating" the color sensor, so it may prove to be useless anyway.
