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

 

Interrupt error report Enable. If enabled, the interrupt signal is High when the IRQ_ERR is set to 1.

 

 

1b

Interrupt error report enable

 

 

0b

Interrupt error report disable

6

IRQ_ERR

 

The Interrupt Error Status bit. It is set to one if an error occurs and there is a Port-Write condition.

 

 

 

Once set, remains set until written with logic 1 to clear.
