14.9.5 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

C Address h0AA; CPU Address:h500
Bit [6]:
Disable MCT speedup aging (Default 0)
1 – Disable speedup aging when MCT resource is low.
0 – Enable speedup aging when MCT resource is low.
Bit [7]:
Slow Learning (Default 0)
1– Enable slow learning. Learning is temporary disabled when search
demand is high
0 – Learning is performed independent of search demand

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.
