how can i know if cortex M0 is von nuemann architecture?

[Apill]

I have seen the block diagram of cortex m0, it has separate lines for code and flash. if it has a separate lines for code and flash( data) why is it called as a "Von Nuemann architecture"

Because there is only on line between the processor core and the bus matrix, i.e. processor reads instructions and data through a shared bus.
