Accessed by serial interface and I 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
2
I C Address h03D; Serial Interface Address h401
2
Accessed by serial interface and I 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)
Note: the number of entries= 66K when T_D[5] is pull down (SRAM memory size = 512K) and 34K when T_D[5] is
pull up (SRAM memory size = 256K).
