Notes:
PRELIMINARY
l The Interrupt operation set to the bit 6 occurs ONLY after the data is not
deleted from Search Table against Deletion command, because there isn’t that
data in Search Table. No other commands are valid.
l The Interrupt operation set to the bit 5 occurs ONLY after a new data is stored
in Search Table by Insertion command but the Entry Counter is not increased,
because a data as which IP address and PL (prefix length –1) are the same
already exists in Search Table. No other commands are valid.
l The Interrupt operation set to the bit 4 occurs ONLY after a new data is not
stored in Search Table against Insertion command, because Search Table is
full. No other commands are valid.
l The Interrupt operation set to the bit 3 occurs ONLY after the executions of
Search/Insert/Delete commands. No other commands are valid.
l The Interrupt operation set to the bit 2 occurs ONLY after the execution of the
Initialize command. No other commands are valid.
l The Interrupt operation set to the bit 1 occurs ONLY after the execution of
either the Insert or Delete command when the values registered in the Entry
Count match those of the Almost Full Register. See the example below:
Example: Entry Count = 999 (3E7h)/Almost Full Register = 1000 (3E8h)
