This field contains the least significant bits of the memory test address for the
selected memory component. Range: 0x00–0xFF
This field contains the middle significant bits of the memory test address for the
selected memory component. Range: 0x00–0xFF
Reserved. Set to 0
1 = When the GTSM is down, ATMUTxClAv for that group is controlled as if all
configured links in the group are Active.
0 = When the GTSM is down, ATMUTxClAv for that group is inactive.
This two bit field determines the use of the PHY side ClAv and En* signals
1 = Bit 7 of the HEC Byte is a HEC error flag
0 = Use the HEC Error checker within the IMA block
0 = mask bits (don’t care)
1 = Check ATMUTxAddr[4] and TMURxAddr[4] for correct value
0 = mask bits (don’t care)
1 = Check ATMUTxAddr[3] and ATMURxAddr[3] for correct value
0 = mask bits (don’t care)
1 = Check ATMUTxAddr[2] and ATMURxAddr[2] for correct value
0 = ClAv and En* for every 4 PHY addresses (support 8 ports total)
1 = ClAv and En* for every 16 PHY addresses (support 32 ports total)
2 = ClAv and En* for all PHY addresses (support 32 ports total)
3 = ClAv and En* for every 8 PHY addresses (support 16 ports total)
