Field Name
Transmit Flow Conductor Bus
The CX28560 sends transmission reports to the system of the number of Dwords (4 bytes)
freed since the previous report. The reports are sent in the form of packets over an 8-bit,
100 MHz POS-PHY bus. The requests packets contain two fields—the channel number
and the number of Dwords freed. From this information the system can maintain an array
of counters that count the amount of space presently available in each of the CX28560’s
channels buffers.
