PM2329 ClassiPI Network Classification Processor Datasheet
4.2.2.20 OC Results FIFO Output Reg (OCRF; Base 1 +00h)
Channel Register
Access Mode: Read Only, Global
The results of packet processing are stored in the Results FIFO, which can be accessed by reading this
register (read port). In 32-bit mode, the upper word (bits 63:32) of this register should be read first.
Regardless of the result of the processing (match, no match, invalid submission, etc.) at least one result is
generated for each OC submitted.
This is a Channel Register; each channel has a corresponding Results FIFO Read Port when the PM2329 is
in the multi-channel mode. When channels are concatenated, the result segments are also concatenated.
Results for the concatenated channel will all be available by reading a single read port corresponding to the
lowest numbered concatenated channel. Reading a Result FIFO Read Port register corresponding to an
