Register 0xC0:

Bit[0] : 0 = Disable the KR4 AN function.

Register 0xB0:

Bit[0] : 1 = Force Negotiate to FEC mode set.

Bit[6:4] : 000 = no force.

Bit[19] : 1 = Force Negotiate to FEC mode.

Note: All change will effect only after “Reset SEQ” bit is set.

Note: For normal two device setup, register 0xB0 and 0xC0 don’t need to change. Only register 0xD0

needs to change to 0x82b85111 for long backplane.

System Monitor Panel

The system monitor panel contains all the error message and status information. The example of the
capture below is one of the error free conditions. The system monitor panel will not refresh
automatically. It needs to manually click on the “Update” button to refresh status.
