Tristate

Function

OD[22:0] is a 23-bit output port. Valid flag, Device ID, Highest

Hit Address (HHA), or Highest Empty Address (HEA) are

output.

Output Port

Output Enable

Input

OEODN is output enable signal for OD[22:0].

Output Port

Input

Bypass Control

When ODBYP is high, the input data to I/O Port (DAT bus) is

output to Output Port (OD bus).

Longest Match

Status Output

Output

LMSTN stays low during the execution of Longest Match

Search.

Synchronous Hit Output

Output

Synchronous

Multi-Hit

Output

Output

SSHON outputs the search results in the device synchronous

with CLK. SSHON low indicates a hit (match) and SSHON high

no entry hit (miss) in the search operation. The SSHON of the

bottom device (Last Device) indicates the hit of a cascaded

system.

SMON outputs the search results in the device synchronous

with CLK. SMON low indicates a multi-hit (multiple matches)

and SMON high no multi-hit in the search operation.

SMON shows the multiple hit status of the device and does not

show the system's status even in the cascaded system.

Priority Hit

Down Input

Input

PHIDN[6:0] connects devices for cascading operations. Refer to

Datasheet.

Priority Hit

Down Output

Output

PHODN[1:0] is used for cascade connection. PHODN[1:0] low

indicates a hit (match) and PHODN[1:0] high no hit entry (miss)

in the search operation.

Priority Hit Up

Input

Input

PHIUN[6:0] connects devices for cascading operations. Refer to

Datasheet.

Priority Hit Up

Output

Output

PHOUN[1:0] is used for cascade connection. PHOUN[1:0] low

indicates a hit (match) and PHOUN[1:0] high no hit entry (miss)

in the search operation.

Priority Multi-Hit Input

Input

PMIN connects devices for cascading operations. Refer to

Datasheet.

Priority Multi-Hit Output

Output

PMON is a output pin that outputs the search results. PMON

low indicates a multi-hit (multiple matches) and PMON high no

multi-hit in the search operation.

The PMON pin of the lowest priority device (Last Device)

indicates the hit signal of the cascaded system.
