When the processor receives execution data, the processor causes an executable program to progress based on the execution data. When the processor receives update data, the processor writes the update data into a memory and causes updating of an update program to progress. When the update of the update program is completed and the programmable device is thereafter reset, the processor ends the executable program and launches the update program as the executable program.
