[bit26] MLK : MediaLB Lock
Indicates whether MediaLB is in sync with the MediaLB frame (lock).
Bit
Description
0
Unlocked state
1
Locked state
When set, it indicates that the MediaLB Port is synchronized to the incoming MediaLB frame.
If MLK is clear (unlocked), MLK is set after FRAMESYNC is detected at the same position for three
consecutive frames. If MLK is set (locked), MLK is cleared after not receiving FRAMESYNC at the
expected time for two consecutive frames. While MLK is set, FRAMESYNC patterns occurring at
locations other than the expected one are ignored.
Note:
−
When MLBn_DCCR:MRS is set to "1", this bit is cleared to "0". When MLBn_DCCR:MDE is "0",
the lock is not detected.
[bit25] MLE : MediaLB Little Endian mode
This field determines how MediaLB data (quadlet-based) is stored in system memory.
Bit
Description
0
Big Endian mode
1
Little Endian mode
[bit24] MHRE : MediaLB Hardware Reset Enable
This bit enables the hardware to automatically reset the MediaLB physical and link layer logic upon
reception of the reset command.
Resetting is preformed by the reset request from the Intelligent Network Interface Controller (INIC).
Resetting is performed when either the global (MLBn_SDCR:MSD = 0x00: all of MediaLB are targeted for
reset) MlbReset (0xFE) or device-specific (MLBn_SDCR:MSD = DA: MediaLB designated by Device
Address is targeted for reset) MlbReset(0xFE) is received from INIC.
Bit
Description
0
Disables resetting upon reception of reset command
1
Enables resetting upon reception of reset command
[bit23] MRS : MediaLB Software Reset
When set, this bit resets the MediaLB physical and link layer. It is cleared automatically by hardware after
the reset execution is complete.
Bit
Description
0
Normal operation
1
Reset
Note:
−
Even when the MLBn_DCCR:MHRE bit is "1" and the reset operation by the receipt of the reset
command is in progress, this bit is reset to "0" after the execution of the reset command.
