Unused. Read 0’s.
TX FIFO Length IMA Group N+4.
Reserved. Write 0’s for normal operation.
TX FIFO Length IMA Group N.
Unused. Read 0’s.
6:0 contains FIFO Length Free Cells
4:0 contains FIFO Length of IMA Groups and Links
Selects FIFO:
000000 - 001111: selects Link FIFO
010000 - 010111: selects IMA FIFO
011000: selects Free Cell FIFO
100000 - 101111: selects ICP Cell Modifier length LINK FIFO
A value of 1 means that all cells are counted for the link N+8. A value of 0 means that all
stuff cells are counted for the link N+8.
A value of 1 enables the IMA mode for the link N+8. A value of 0 enables the non-IMA
mode for the link N+8.
A value of 1 enables the descrambling of the cell for the link N+8.
When set to 1, count all USER cells for link N+8,
when cleared to 0, count Filler/Idle/Unassigned cells for link N+8.
A value of 1 means that the Unassigned and Idle cells are discarded upon reception for
the link N+8.
A value of 1 enables the discard option of the cells with wrong HEC. A value of 0 will
disables the discard option, all the cells will be written to the receive buffer.
