PM2329 ClassiPI Network Classification Processor Datasheet
OC Identifier Format
Each OCID has 15-bits, these fields are defined as follows:
Bit [14] D-Word Present: If this bit if set to
1
, it indicates that D-Words corresponding to this OC
are present in the E-RAM. If this OC results in a match condition, the D-Words will be updated
depending on the setting of the D-Word Update Control field in the C-Word. The C-Word and D-
Word are fetched from the E-Word corresponding to the matched cell.
When performing OCC controlled sequencing, fields other than the D-Word Update Control field in
the C-Word are ignored.
Bits [13:8] OC Descriptor Index: This field specifies the index of the descriptor in the OC Descriptor
table which will be used for executing this OC.
Bits [7:0] Cascade OC Enable: This field specifies which of the eight PM2329 devices in the cascade
will participate in the OC. When the enable bit is set, the corresponding device will execute the OC.
If the enable bit is reset, the corresponding device will not execute the OC. Bit 0 corresponds to
PM2329 device 0, bit 7 corresponds to PM2329 device 7 in the Cascade.
If this field is set to 00h (i.e., all devices are disabled), it signals an invalid OCID and the current OC
execution will be terminated and the following OCIDs, if any, will be ignored. Bits [14:8] of the
OCID in this case are not used and should be set to zeroes.
