22 events. Commands are sent to the EC and may have a different implications in
23 different contexts. Events are sent by the EC upon some internal state
25 initiated by the EC.
44   The command is accepted by the EC as a valid command and acknowledged
45   (following the standard communication protocol), but the EC does not act
72 Note that the detachment process is governed fully by the EC. The
73 ``surface_dtx`` driver only relays events from the EC to user-space and
74 commands from user-space to the EC, i.e. it does not influence this process.
80 1. The EC turns on the indicator led on the detach-button, sends a

89 3. The EC waits for instructions from user-space and acts according to them.
90    If the EC does not receive any instructions in a given period, it will

98    - If the latch is locked, the EC will *not* open the latch, meaning the
