5.90 Port Error Rate Threshold CSR n (SPn_ERR_THRESH)
SRIO Registers
Each of the four ports is supported by a register of this type (see ). The port error rate threshold CSR n
(SPn_ERR_THRESH) is shown in
Figure 153 and described in Table 175 .

Bit Field Value Description
31–24 ERROR_RATE_FAILED_THRESH These bits provide the threshold value for reporting an error
condition due to a possibly broken link.
00h Disable the error rate register
01h Set the error reporting threshold to 1
02h Set the error reporting threshold to 2
... ...
FFh Set the error reporting threshold to 255
23–16 ERROR_RATE_DEGRADED_THRESH These bits provide the threshold value for reporting an error
condition due to a degrading link.
00h Disable the error rate Register
01h Set the error reporting threshold to 1
02h Set the error reporting threshold to 2
... ...
FFh Set the error reporting threshold to 255
15–0 Reserved 0000h These read-only bits return 0s when read.
