used. The upper 2 bits are for the future expansion purpose.
The RSS_ring value for entry 122. Only the least significant 2 bits are
used. The upper 2 bits are for the future expansion purpose.
The RSS_ring value for entry 123. Only the least significant 2 bits are
used. The upper 2 bits are for the future expansion purpose.
The RSS_ring value for entry 124. Only the least significant 2 bits are
used. The upper 2 bits are for the future expansion purpose.
The RSS_ring value for entry 125. Only the least significant 2 bits are
used. The upper 2 bits are for the future expansion purpose.
The RSS_ring value for entry 126. Only the least significant 2 bits are
used. The upper 2 bits are for the future expansion purpose.
The RSS_ring value for entry 127. Only the least significant 2 bits are
used. The upper 2 bits are for the future expansion purpose.
