5.1.3
In all the asynchronous receive modes, the packet header information is always loaded into the header
registers. In quadlet receive mode, the first three header quadlets are loaded into the header0at 38h,
header1at 3Ch, and header2at 40h registers, respectively. The trailer quadlet is loaded into the trailer
register at 48h. In block receive mode, the only additional step performed is loading the fourth header
quadlet received into the header3 register at 44h.
Asynchronous Receive
5.1.3.1
Asynchronous Packet Receive Without Headers and Trailer
Step 1:
Asynchronous packet is received through the receiver logic of the link core
Step 2:
The packet headers are stripped off from the packet and loaded into the header registers:
a)
If in quadlet receive mode, the three header quadlets are loaded into the header0
–
header2 registers.
b)
If in block receive mode, the four header quadlets are loaded into the header0
–
header3 registers.
Step 3:
Packet data (payload only) is routed directly to the DM port without any buffering.
Step 4:
Trailer quadlet is loaded into the trailer register at 48h
