83 green. If the latch has been locked, the led will be solid red
93 - If the latch is unlocked, the EC will open the latch and the clipboard
98 - If the latch is locked, the EC will *not* open the latch, meaning the
111 latch, after which the user can separate clipboard and base.
113 As this changes the latch state, a *latch-status* event
114 (``SDTX_EVENT_LATCH_STATUS``) will be sent once the latch has been opened
