7.3.3
For SSRAM (connected to the NSE) Read or Write operations,
Data 0 is used to pass the SSRAM address and SEID. Data 1
is used for passing the data for a Write operation. Table 7-9
shows the format for Data 0 and Data 1 for accessing the
SSRAM.
Table 7-9. SSRAM Data
For NSE Read and Write operations, the Data 0 is used to
pass address and SEID. Data 1 is used for passing data for
Write operations. This 64-bit Data 1 field holds data[67:4] for
the NSE, while data[3:0] is held in the layer attribute and valid

These two registers return the result of the Read operation in
two 64-bit words. Result Register 0 contains the four least

Done. This field indicates that the Read operation is complete.
When the done bit is set, the next command can be written in
the descriptor. The done bit is cleared when the Result
Register 0 is Read by the network processor.

Result Register 1 contains the SE Data[67:4] Read from the
NSE (Table 7-12) or Data[63:0] Read from the SSRAM
connected to the NSE (Table 7-13).
