Description
17
MAX_RETRY_EN
Max_retry_error report enable. If enabled, the Port-Write and interrupt are reported as errors.
1b
Max retry error report enable
0b
Max retry error report disable
16
MAX_RETRY_ER
Max_retry_error bit is set when max_retry_cnt is equal to max_retry_threshold. The Port-Write
R
request and interrupt are generated if enabled. This bit is ignored if max_retry threshold is 00. Once
set, it remains set until written with logic 1 to clear. This bit also is cleared by writing all 0s to the
register SP0_ERR_DET. This error also reported in register SP0_ERR_DET.
15-8
MAX_RETRY_TH
Maximum Retry Threshold Trigger. These bits provide the threshold value for reporting an error
R
condition due to possibly broken partner behavior.
00
Disable the max_retry_error reporting
01
Set the max_retry_threshold to 1
02
Set the max_retry_threshold to 2
...
FF
Set the max_retry_threshold to 255
7
IRQ_EN

1b
Interrupt error report enable
0b
Interrupt error report disable
6
