Yes again another mistake.... I assumed the SPIx->DR Register would be overridden.The new Code works without a problem. Thank you guys very much. Since I'm very new to this low level type of programming without any HAL oder Arduino libraries this cod...

Ok after adding toggling and adding the CS Pin the MISO line works as well and also the data which is transmitted seems to be correct. The MPU6500 should send 0x70 and on the oscilloscope it looks like this value. Nevertheless am I still receiving ju...
