  35 # As long as the power-loss flag is set, all target-side pins are
  36 # high-Z except the EMU-pins for which the opposite holds unless
  37 # EMU_EN is high.
  38 #
  39 # To use wait-in-reset, drive EMU0 low at power-on reset. If the
  40 # target normally reuses EMU0 for other purposes, clear EMU_EN to
  41 # keep the EMU pins high-Z until the target is power-cycled.
  42 #
  43 # The LED only turns off at USB suspend, which is also the only way to
  44 # set the power-loss flag manually. (Can be done in software e.g. by
  45 # changing the USB configuration to zero.)
