14.8.3 +SCAN – SCAN Control Register (default 00)
CPU Address h404
Accessed by CPU (R/W)
SCAN is used when fast learning is enabled (SE_OPMODE bit 0). It is used for setting up the report rate for newly
learned MAC addresses to the CPU.
Examples:
R= 0, Ratio = 0:
All rounds are used for aging. Never scan for new MAC addresses.
R= 0, Ratio = 1:
Aging and scanning in every other aging round
R= 1, Ratio = 7:
In eight rounds, one is used for scanning and seven are used for aging
R= 0, Ratio = 7:
In eight rounds, one is used for aging and seven are used for scanning

Ratio
Bit [6:0]:
Ratio between database scanning and aging round (Default 00)
Bit [7]:
Reverse the ratio between scanning round and aging round (Default 0)

FCBAT
Bit [7:0]:
FCB Aging time. Unit of 1ms. (Default FF)
This is for buffer aging control. It is used to configure the buffer aging
time. This function can be enabled/disabled through bootstrap pin. It is
not suggested to use this function for normal operation.
