31.1

mg_power_indicate

_disable

R/W

IP113M LF power abnormal indication

disable

1: IP113M LF does not send out

maintenance frame with power abnormal

message when its power is abnormal

0: IP113M LF sends out maintenance

frame with power abnormal message

when its power is abnormal

31.2

TP_link_list_fail

0: TP port memory link list is ok

This bit is always 0, if IP113M LF is in

normal operation.

31.3

Fiber_link_list_fail

Fiber port link list failure indication

1: Fiber port memory link list fails

0: Fiber port memory link list is ok

This bit is always 0, if IP113M LF is in

normal operation.

31[5:4]

BIST_status

BIST Status of embedded SSRAM

bit[4] : memory is under testing

1: under testing, 0: testing over

bit[5] : memory test result is good when

testing over

1: good, 0: fail

Bit[5:4] is “01” at the end of reset. After

BIST, If the test result is ok, it becomes

“10”, otherwise it shows “00”.
