Description
000 = Reserved (Do Not Use)
001 = 32us (default)
010 = 128us
011 = 256us
100 = 512us
101 = 1ms
110 = 2m
111 = 4ms
To send a maintenance frame, an external controller writes to these command
bits via the SMI, SPI, or I2C interface.
Other values : N/A
Note
0 0000 : No request
0 0001 : Send “Condition Inform Request” frame
0 0010 : Send “Loop Mode Start Request” frame
0 0100 : Send “Loop Mode Stop Request” frame
0 1000 : Send “Remote Command”. Here, the Maintenance frame will be made
1 0000 : Send “Indicate Center/Terminal MC Condition” frame. Usually,
Except for the “Indicate Center/Terminal MC Condition” frame, all
maintenance frames here are sent by the Center side MC only.
1 = Full duplex
1 = AN enable
Description
1 = 100Mbps
0 = 10Mbps
This bit share the same physical register as Reg. 2Ch bit 6.
0 = Half duplex
This bit share the same physical register as Reg. 2Ch bit 5.
0 = AN disable
This bit share the same physical register as Reg. 2Ch bit 7.
up of the “Condition Inform Request/Reply” frame, but the My Model
Info bits MM24-MM47 will be mapped to Registers 4Ah-4Ch, instead
of Registers 55h-57h.
“Indicate Center/Terminal MC Condition” frame will be sent
automatically. But this OAM frame can be sent manually using this
command.
