SRIO Registers

5.75 Logical/Transport Layer Error Detect CSR (ERR_DET)

This register allows for the detection of logical/transport layer errors. The detectable errors are captured in the fields shown in Figure 138 and described in Table 151. For additional programming information, see Section 3 .

Bit

Field

Value

Description

 

31

IO_ERR_RSPNS

 

I/O error response (endpoint device only)

 

 

 

0

An LSU did not receive an ERROR response to an I/O logical layer request.

 

 

 

1

An LSU received an ERROR response to an I/O logical layer request. To clear

 

 

 

 

this bit, write 0 to it.

 

30

MSG_ERR_RSPNS

 

Message error response (endpoint device only)

 

 

 

0

The TXU did not receive an ERROR response to a message logical layer

 

 

 

 

request.

 

 

 

1

The TXU received an ERROR response to a message logical layer request. To

 

 

 

 

clear this bit, write 0 to it.

 

29

Reserved

0

This read-only bit returns 0 when read.

 

28

ERR_MSG_FORMAT

 

Error in message format (endpoint device only)

 

 

 

0

The RXU did not receive a message data payload with an invalid size or

 

 

 

 

segment.

 

 

 

1

The RXU received a message data payload with an invalid size or segment. To

 

 

 

 

clear this bit, write 0 to it.

 

27

ILL_TRANS_DECODE

 

Illegal transaction decode (switch or endpoint device)

 

 

 

 

For an LSU or the TXU:

 

 

 

0

The LSU/TXU did not receive illegal fields in the response packet for an

 

 

 

 

IO/message transaction.

 

 

 

1

The LSU/TXU received illegal fields in the response packet for an IO/message

 

 

 

 

transaction. To clear this bit, write 0 to it.

 

 

 

 

For the MAU or the RXU:

 

 

 

0

The MAU/RXU did not receive illegal fields in the request packet for an

 

 

 

 

IO/message transaction.

 

 

 

1

The MAU/RXU received illegal fields in the request packet for an IO/message

 

 

 

 

transaction. To clear this bit, write 0 to it.

 

26

Reserved

0

This read-only bit returns 0 when read.
