Logic analyzer setup
--------------------

The logic analyzer used was an ARMFLY Mini-Logic (at 24MHz):

  Probe       MK220
  -----------------
  0           DM
  1           DP


mk220.sr
--------

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=24mhz --time 1s -o mk220.sr --probes 1,2

(the mouse was moved while running this command)
