A read accesses the byte #2 and byte #1 of the Counter that was selected in the Select
Counter register. Byte 2 is in bits 15:8 and byte 1 is in bits 7:0.
A write will hold the value to be written to the selected counter.
Unused. Read all 0’s.
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, (or User Cells)
0110: TX Link, number of Idle/Filler cells
0101: TX Link, number of Stuff cells
0100: TX Link, number of ICP cells
0011: RX Link, total number of cells (or stuff cells)
0010: RX Link, number of Idle/Filler cells, (or User Cells)
0001: RX Link, number of cells with HEC errors
0000: RX Link, number of bad ICP cells
Other values are not valid and should not be used.
The valid bit combinations are:
10111: IMA Group 7 when UTOPIA Input counter access
10010: IMA Group 6 when UTOPIA Input counter access
...
10001: IMA Group 1 when UTOPIA Input counter access
10000: IMA Group 0 when UTOPIA Input counter access
01111: Link 15
01110: Link 14
...
00000: Link 0
Other values are not valid and should not be used.
