Reserved.
Each bit reports the recombination status for a link. A 1 means that the recombination is
enabled. The bit 3 reports for link 3 and so on so forth. Do not write to this register.
Unused. Read all 0’s.
Recombiner Control: 1 to enable the recombiner and a 0 to disable. This bit works in
conjunction with the RX Recombiner Delay register.
These 2 bits specify which IMA Group the link belongs to:
00: IMA Group #0
01: IMA Group #1
10: IMA Group #2
11: IMA Group #3.
Reserved. Write 0 for normal operation.
A 1 enables the circuitry to wait for the first User cells to be received before adding the
link 3 to the recombiner process. A 0 will include the link 3 in the recombiner as soon as it
is enabled in the RX Recombiner register.
A 1 enables the circuitry to wait for the first User cells to be received before adding the
link 2 to the recombiner process. A 0 will include the link 2 in the recombiner as soon as it
is enabled in the RX Recombiner register.
A 1 enables the circuitry to wait for the first User cells to be received before adding the
link 1 to the recombiner process. A 0 will include the link 1 in the recombiner as soon as it
is enabled in the RX Recombiner register.
A 1 enables the circuitry to wait for the first User cells to be received before adding the
link 0 to the recombiner process. A 0 will include the link 0 in the recombiner as soon as it
is enabled in the RX Recombiner register.
