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

The logic analyzer used was a Saleae Logic (at 6-24MHz):

  Probe       Pin
  ---------------
  0           START
  1           STOP
  5           DATA
  7           CLOCK

The sigrok command line used was:

  sigrok-cli -d fx2lafw -c samplerate=24MHz -o <filename> --time 1s

Time, samplerate and <filename> parameters vary depending on the file.
