Reserved Bits are Read as Zero Unless Otherwise Stated.
Figure 26. Personality Register
Reserved (bits 15:6)
Reserved
These bits are reserved for future use. These bits should
always be written with zeroes to ensure compatibility
with future revisions of the AF. These bits will always
read back as zeroes.
SKIP (bit 5)
Skip This Entry
This bit prevents the associated entry from indicating a
match during a “Find” operation begun through the
command register. This bit has no effect on compari-
sons with comparands received from the MAC interface.
SAX (bit 4)
Source Address Exact
This bit causes the AF to indicate that any comparison
matching this CAM entry to a source address will be
indicated as being an exact match. An exact match may
contain masking done while comparing the entry. Invalid
if SA is zero.
SA (bit 3)
Source Address
This bit enables the CAM entry for comparison with
source addresses.
DAX (bit 2)
Destination Address Exact
This bit causes the AF to indicate that any comparison
matching this CAM entry to a destination address will be
indicated as being an exact match. An exact match may
contain masking done while comparing the entry. Invalid
if DA is zero.
DA (bit 1)
Destination Address
This bit enables the CAM entry for comparison with
destination addresses.
Valid (bit 0)
CAM Entry Valid
This bit indicates that the CAM entry is valid and is
enabled for comparisons with addresses indicated by
the SA and DA bits.
