1.6.2.2
Error Threshold Divider Register
Address = 200\h.
Write only.
The Error Threshold divider register is a 3-bits value which helps with the Block Size value to generate the Error Threshold.
BIT
2..0
DESCRIPTION
Error Threshold divider :
000 : Disable Threshold
001 : Block size / 2
010 : Block size / 4
011 : Block size / 8
100 : Block size / 16
101 : Block size / 32
110 : Block size / 64
111 : Block size / 128
31:3
Not used.
The possible Error Threshold value are :
BLOCK SIZE
00 : 128 cells
01 : 256 cells
10 : 512 cells
11 : 1024 cells
Possible Error Threshold Value
1, 2, 4 …….64 or disabled
2, 4, 8 …….128 or disabled
4, 8, 16 … 256 or disabled
8, 16, 32 ….512 or disabled
If the Error Threshold divider is programmed to 000 it means the comparison with the Error Threshold Value is inhibited. Hence
the Ingress CLP0+1 Errored Cells counter (Stat. B) is always incremented when a block is received with errored cells.
Conversely, the Ingress Severely Errored Cell Blocks counter (Stat. A) is not incremented regardless of the number of Cells
Errored in a given block.
1.6.2.3
Lost Threshold Divider Register
Address = 204\h.
Write only.
The Lost Threshold divider register is a 3-bits value which helps with the Block Size value to generate the Lost Threshold.
BIT
2..0
DESCRIPTION
Lost Threshold divider :
000 : Disable Threshold
001 : Block size / 2
010 : Block size / 4
011 : Block size / 8
100 : Block size / 16
101 : Block size / 32
110 : Block size / 64
111 : Block size / 128
