C Address h03A; Serial Interface Address:h20E
Accessed by serial interface and I
2
C (R/W)
Port Selection in unmanaged mode. Trunk group 2 and Trunk group 3 are enable accordingly to bits [1:0] when
input pin P_D[10] = 0 (External pull down).
10.4.3 TX_AGE – Tx Queue Aging timer
I
2
C Address: h03B;Serial Interface Address:h312
Accessed by serial interface and I
2
C (R/W)
Bit[4:0]: Unit of 100ms (Default 8). Disable transmission queue aging if value is zero.
Bit[7:5]: Reserved. (Must be '0')
10.5 Group 4 Address - Search Engine Group
10.5.1 AGETIME_LOW – MAC address aging time Low
I
2
C Address: h03C; Serial Interface Address:h400
Accessed by serial interface and I
2
C (R/W)
Bit [7:0] Low byte of the MAC address aging timer. (Default 2c)
Mac address aging is enable/disable by boot strap T_D[9].
10.5.2 AGETIME_HIGH –MAC address aging time High
I
2
C Address h03D; Serial Interface Address h401
Accessed by serial interface and I
2
C (R/W)
Bit [7:0]: High byte of the MAC address aging timer. (Default 00)
Aging time is based on the following equation:
{AGETIME_HIGH,AGETIME_LOW} X (# of MAC entries X100μsec)

Bit [1:0]:
Port member selection for Trunk 2 and 3 in unmanaged mode
00 – Only trunk group 2 is enable. Port 4 and 5 are used for trunk group2
01 – Only trunk group 2 is enable. Port 4, 5 and 6 are used for trunk group2
10 – Only trunk group 2 is enable. Port 4, 5, 6 and 7 are used for trunk group2
11 – Trunk group 2 and trunk group 3 are enable. Port 4 and used for trunk group2, and port 6 5 are
and 7 are used for trunk group3
