Simultaneous High speed USB transfer with eDMA transfer

Using a K64 MCU - MK61FN1M0VMJ12

 

I want to transfer data into memory from an external peripheral AND transfer data from memory via high speed USB at the same time.  Currently I am doing these operations sequentially.

I can't find information about the relative priority of the two BUS masters, is it documented?

I assume the two transfers will share the bus, only using the cycles needed.

Can anyone point me to some documentation on the topic?
