RE: ATA + SyncSer + USB?


Unfortunately ATA uses all the groups even if you don't
use all the ports. ATA is therefore multiplexed with one 
synchronous port while USB is multiplexed with the other.

I can't think of any solution to this right now but I
will get back to you if I come up with one.

Subject: ATA + SyncSer + USB?


We are trying to figure out a way to connect ATA disk, an USB peripheral
and a SyncSerial peripheral into ETRAX100LX, all at once. We don't need
channels 2-3 on ATA interface, so is it possible to somehow assign I/O
group C to synchronous serial port p3 and the groups A, B and D to ATA?

The register definitions of LX does not seem to be ready, and the older
version's regdef document does not implicitely tell whether this is

Thank you in advance!
