We are using the nRF5340 and our use case makes full use of all 4 shared peripherals for SPI and TWI as well as SPIM4. We want to add UART over USB and I was able to port over the CDC-ACM example without much issue and noticed that it was not declaring any of the shared peripherals as far as I could tell. My understanding is that the CDC-ACM example utilizes the USBD peripheral instead of a UARTE and thus should work without conflict to any of our existing peripherals.
I have been unable to find clear documentation stating either way, so I would just like to get some confirmation.
Thanks,
