Yes, you are correctly understood.Sory for my English:)

I have created SOPC-component of Master Avalon-MM with conduit input (like DMA-controller).

My master need to hold a bus (same as DMA-controller). What signal I can use for holding bus? lock? I can't find documentation witch explain arbitration on Avalon bus. I known only about AN184 (extras.springer.com/2001/978-0-306-47635-8/an/an184.pdf).

Thank you.
