This field contains the least 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 Enb* signals. When using
Utopia-to-Serial mode, PHY Size should be set to 16 ports per Clav and En*. Thus for
M28525, PHY Size should be 2 while for M28529, PHY Size should be 1.
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)
high when PHY Size is set to 2.
(Ports 0-3 assigned to Clav0/Enb0*)
(Ports 4-7 assigned to Clav1/En1*)
(Ports 0-15 assigned to Clav0/Enb0*)
(Ports 16-31 assigned to Clav1/Enb1*)
(Ports 0-31 assigned to Clav0/Enb0*)
(Ports 0-7 assigned to Clav0/Enb0*)
(Ports 8-15 assigned to Clav1/Enb1*)
For Utopia-to-Utopia mode, PhyUrxEna[1] and PhyUtxEna[1] should be pull
