  • Runnable_00_blink_Tick
  • Runnable_blink_Button_IN
  • Runnable_00_blink_OUT
run_UART_wakeUp

Runnable to switch into the UART state if there is an event in the Blink State.
This runnable does not use hardware signals but accesses hardware directly and is therefore associated with
an protection set grandting access to hardware.
