Procedures and Input data for this test.
Procedures and input-data

Regular power-on with a terminal connected to UART. The Button is pressed for 10 seconds.
Expected results for this test
Expected results

The string '--- UART WakeUp ----' is send whenever the button is pressed, followed by 'Button pressed for %d seconds.' messages, where '%d' represents the integer number of seconds the button already has been pressed.

Requirement_95 - UART

When the button is pressed, the system-state shall change from Blink into UART mode.
The start of UART mode shall be signaled via UART.
As long as the button is pressed, UART strings with the time in seconds the Button was pressed shall be send with the frequency with which the button pressed signal is updated.

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.
