1. Call the following parameters to start the system function:
2. Check the return value:

– reqActDeactGetStateMode = REQUEST_TRUE
– nextCommand = WHEN_COMMAND_DONE
– A return value < 0 indicates that the function has been terminated with errors. You can
program error routines, depending on the return value.
– The return values 16#0000_0001, 16#0000_0002, 16#0000_0005, and 16#0000_0006
indicate that the function has been completed without errors.
