  22 # In SWD mode, the JTAG_EN signal doubles as SWO_EN_N which switches the
  23 # second FTDI channel UART RxD to the SWO pin instead of the separate RxD
  24 # pin. Note that the default init state has this pin high so when OpenOCD
  25 # starts in SWD mode, SWO is by default disabled. To enable SWO tracing,
  26 # issue the command 'ftdi set_signal SWO_EN 1' where tracing is configured.
  27 # To switch back to using the separate UART, SWO_EN needs to be disabled
  28 # before exiting OpenOCD, or the adapter replugged.
