- Has anybody out there had any experience using the SCC68070
- microprocessor from Philips?
-
- I am trying to get the I^2C and DMA facilities working but have run
- into a few problems.
-
- The first problem is that the DMA does not seem to work at all.
- After initialising the appropriate registers I start the DMA
- channel, and it justs sits there. It does not matter what sort of
- operation I try it's allways the same result, NOTHING.
-
- The second problem is with the I^2C bus. Everything works ok but I
- cannot get it to generate a STOP bit.
-
- If anyone can help please E-MAIL me rather than posting a reply as I
- may miss it.
-
- Thanks in advance,
-
- Terry Edhouse.
