7.0 RIC2A Registers (Continued)
CAM Location Mask Register (CLMR) (Pages 9H, AH, BH, CH, DH, EH, FH)
Each shared CAM has a CLMR, therefore there are 32 CLMRs. Any of the 32 CAMs can be shared among the ports. For
example, multiple ports can share a single ethernet address, or multiple addresses can be associated with a single port.
Assigning CAMs to ports, or vice-versa, is done through these registers.
