The valid bit combinations are:
1011: UTOPIA Input, counter of all cells for link
1010: UTOPIA Input, counter of Idle cells for link
1001: UTOPIA Input, counter of Unassigned cells for link
1000: UTOPIA Input, counter of cells with HEC error, single or multiple bit errors
0111: TX Link, total number of cells
0110: TX Link, number of Idle (or User Cells)
0011: RX Link, total number of cells
0010: RX Link, number of Idle (or User Cells)
0001: RX Link, number of cells with HEC errors
Other values are not valid and should not be used.
The valid bit combinations are:
01111: Link 15
01110: Link 14
...
00000: Link 0
Other values are not valid and should not be used.
Each bit represents a link. A ’1’ means that the interrupt form the corresponding link is
enabled and that the level of the IRQ pin is low if the corresponding bit in the IRQ Master
Register is set. A’0’ means that the IRQ level is not affected by the corresponding bit.
