Figure 1-166. Inbound Data Transfer Descriptor Format
Figure 1-167. Outbound Data Transfer Descriptor Format
The general data transfer Descriptor formats can be seen in the above figures. The descriptor consists of
8 32 bit words. A Data Transfer Descriptor will be removed from the list when the resource specified by
the Channel field is free. If the Channel is not free when the list reaches a data transfer descriptor then the
list will stall until the current transfer on the channel has completed.
