Description

Sends a data fragment to the specified channel. If data packets are supported, applications must ensure consistent usage of SOP and EOP in each channel. Except for the last segment in a packet, the length of each segment is a multiple of the data width.

If data packets are not supported, applications must ensure that there are no SOP and EOP indicators in the data. The length of each segment in a packet is a multiple of the data width.
