|
|
|
# To use wait-in-reset, drive EMU0 low at power-on reset. If the |
|
|
|
# target normally reuses EMU0 for other purposes, clear EMU_EN to |
|
|
|
# keep the EMU pins high-Z until the target is power-cycled. |

|
# The LED only turns off at USB suspend, which is also the only way to |
|
|
|
# set the power-loss flag manually. (Can be done in software e.g. by |
|
|
|
# changing the USB configuration to zero.) |
