7.0 RIC2A Registers
Shared CAM Validation Register 4 (SCVR 4) (Page 9H Address 19H)
This register indicates the validity of an Ethernet address stored in any one of the shared CAMs. When a “1” is written in
a specific SCVR, upon starting the network security, the CAM contents will be used for address comparison.
Note: Before writing to and changing any bits in this register, read the register first and then only change the desired bits. By doing this, a previous entry will
not be invalidated mistakenly.
