CSIX-L1 Multicast Mask, Multicast Binary Copy and Broadcast frames are not supported by this bridge since there
are no equivalent features in the PI40 protocol. CSIX Flow Control Cframes are never received in the CSIX inbound
direction in this application.
Cframe data is read from the ingress FIFO and inspected for SOF and EOF indications as long as the FIFO empty
?ag is not asserted (i.e. as long as there is data in the FIFO). Detection of an SOF indicates the beginning of a new
Cframe/cell.
The Cframe header information is inspected and mapped to PI40 cell header as follows:
?
Unicast Cframe mapping:
- RES = 0
- EBP = 1 if CSIX Ready = 0 or outbound FIFOs exceed high watermark, else EBP = 0
- TRCLASS = top 3 bits of CSIX Class
- MC = 0
- PSW_ID = provisionable
- RQN = 0
- DESTP = bottom ten bits of CSIX Destination
