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