Force
Speed Setting (0-7) (Reg31H), default = 0xFF00H
BIT
DESCRIPTION
TYPE
DEFAULT
31.7-0
N/A
31.15-8
Force Speed Operation
When auto-negotiation off, the port will be set at fixed speed.
In
EEPROM, force settings will be automatically written into PHY registers at
initialization.
Force settings by CPU requires extra CPU write operation
into PHY; so port-base speed operations can keep consistency.
One bit
per port; e.g. bit 8 for port 0 and bit 15 for port 7.
0 : force 10Mbps
1 : force 100Mbps

Force Half Duplex Operation
When auto-negotiation off, the port will be set at fixed duplex.
In
EEPROM, force settings will be automatically written into PHY registers at
initialization.
Force settings by CPU requires extra CPU write operation
into PHY; so port-base duplex operations can keep consistency.
One bit
per port; e.g. bit 0 for port 0 and bit 15 for port 15.
0 : force half duplex
1 : force full duplex
R/W
0xFFFFH
