168 / 444 page  Functional Descriptions VMDS-10492 VSC7440 Datasheet Revision 4.2 151 3.20.1 VCAP IS2 Keys VCAP IS2 supports a number of different keys that can be used for different purposes and frame types. The keys are of type X4, X8, or X16 depending on the number of words each key uses. The keys are grouped after size as shown in the following table. The following table lists details for all VCAP IS2 keys and fields. When programming an entry in VCAP IS2, the associated key fields must be programmed in the listed order with the first field in the table starting at bit 0 in the entry. As an example, for a MAC_ETYPE entry, the first field X8_TYPE must be programmed at bits 3:0 of the entry, the second field FIRST must be programmed at bit 4, and so on.
