Bus mastering in ColdFire 5272?

Dec 18, 2003 0 Replies

Hello, first, sorry if you see this post twice - I've already posted this question through our ISP's news server but it didn't show up after almost a full day, so I'll repost it via Google.



Does anyone know how to set up priorities of different bus masters in Motorola's ColdFire 5272 (there are three - NIC's DMA, user controlled DMA processor and CPU)? Unfortunately, I can't find anything relevant in the Motorola's documentation. Any piece of initialization code (assembly or C) or a reference to a specific place in the documentation would be greatly appreciated.



Thanks in advance, Arkady.
