Input

OEODN is output enable signal for OD[23:0]. This signal is also

referenced to CLK rising edge.

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

output to Output Port (OD bus).

LMSTN stays low during the execution of Weighted Search.

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.

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

the data sheet.

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.

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

the data sheet.

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.

PMIN connects devices for cascading operations. Refer to the

data sheet.

PMON

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.
