Cell Scrambling. A 1 enables the scrambling of the cells on the link N+8.
Defines IMA group number when the link is configured in IMA mode. Select the IMA group
Write 1 to count all User cells sent on the TX TDM link N+8.
Write 0 to count the total number of cell sent on the TX TDM link N+8.
Set to 1 to start sending User Cells in IMA mode on link N+8.
Set to 0 to send always Filler and ICP cells in IMA mode
(Note: in non-IMA 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.
Set to 1 for non-IMA mode and clear to 0 for IMA mode. Select the IMA group number
BEFORE enabling the IMA mode.
number BEFORE enabling the IMA mode. When configuring the link in non-IMA mode
after it was in IMA mode, do not change the IMA group number until the link is reported in
non-IMA mode (refer to TX IMA Mode Status Register).
Write 1 to count all User cells sent on the TX TDM link N.
Write 0 to count the total number of cells sent on the TX TDM link N.
Set to 1 to start sending User Cells in IMA mode.
Set to 0 to send continuously Filler and ICP cells in IMA mode
(Note: in non-IMA 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.
Set to 1 for non-IMA mode and clear to 0 for IMA mode. Select the IMA group number
BEFORE enabling the IMA mode.
Defines the ICP cell offset of link N. The value of M determines which significant bits are
used as follows:
M=256; bits 7-0 are used,
M=128; bits 6-0 are used,
M=64; bits 5-0 are used,
M=32; bits 4-0 are used.
link 1 with link 9, and so on.For MT90222 only groups 0,1,2 and 3 are used.
The MSByte contains control the link 8-9 and LSByte control links 0-7
0x0318 - 0x031F (8 reg)
1 register per 2 links, link 0 is paired with link 8, link1 with link 9 and so on.
0808
0x0310 - 0x0317 (8 reg)
1 register per 2 links, used in IMA mode only. Link 0 is paired with link 8,
