RUN-STOP
In this mode, the execution of the user application is stopped. The RUN-STOP mode can be used
to upload a new application to the device. It can be useful if the system menu is unavailable, e.g.
the application is corrupted and / or leads to unstable operation.
To activate the RUN-STOP mode, power on the device with the button
pressed.
