1, start the chip when external pins (PS1, PS0) = (1,0)
Note: in (PS1,PS0) = (0,0) mode, the chip will
start automatically, after trying to read the external
EEPROM. If EEPROM does not exist, the chip will use
default values for all internal registers. If EEPROM is
present, the contents in the EEPROM will be checked.
The switch will check:
override chip register default values =0, chip will not
start when external pins
(PS1, PS0) = (1,0) or (0,1).
Note: (PS1, PS0) = (1,1) for Factory test only.
0, stop the switch function of the chip.
New Back-off algorithm designed for UNH
1 = Enable
0 = Disable
Reserved.
Flush the entire dynamic MAC table for RSTP
1 = Trigger the flush dynamic MAC table operation.
This bit is self clear
0 = normal operation
Note: All the entries associated with a port that has its
learning capability being turned off (Learning Disable)
will be flushed. If you want to flush the entire Table, all
ports learning capability must be turned off.
Flush the matched entries in static MAC table for
RSTP
1 = Trigger the flush static MAC table operation. This
bit is self clear
0 = normal operation
Note: The matched entry is defined as the entry
whose Forwarding Ports field contains a single port
and MAC address with unicast. This port, in turn, has
its learning capability being turned off (Learning
Disable). Per port, multiple entries can be qualified as
matched entries.
If this check is OK, the contents in the EEPROM will
