Reserved, write 0 for normal operation.
Set to 1 to start sending User Cells in IMA mode.
Set to 0 to send always Filler and ICP cells in IMA mode
(Note: in UNI mode, the control to send User cells is implemented with the UTOPIA Input
Link PHY Enable register).

Coset value. A 0 will generate HEC with Coset value, when 1, Coset is not added.
Cell Scrambling. A 1 enables the scrambling of the cells on the link N.
Reserved, must write a 0 for normal operation.
Set to 1 for UNI mode and clear to 0 for IMA mode. Select the IMA group number
BEFORE enabling the IMA mode.
1:0
R/W
Defines IMA group number when the link is configured in IMA mode. Select the IMA group
number BEFORE enabling the IMA mode. When configuring the link in UNI mode after it
was in IMA mode, do not change the IMA group number until the link is reported in UNI
mode (refer to TX IMA Mode Status Register).
