TX_FLW

 

Transmit Link Flow Control enable

 

 

0b

Disables transmit flow control (Enables receive link flow control)

 

 

1b

Enables transmit flow control (not supported)

29

SOFT_REC

 

Software controlled error recovery.

 

 

0b

Transmission of error recovery sequence is performed by the hardware

 

 

1b

Transmission of error recovery sequence is performed by the software. By default the transmission

 

 

 

error recovery sequence is performed by the hardware. If this bit is set, the hardware recovery is

 

 

 

disabled and the hardware transmission logic must wait until software has written the register Port n

 

 

 

Local ackID Status CSR.

Reserved

26

FORCE_REINIT

 

Force reinitialization process. In 4x mode this bit affects all 4 lanes. This bit is write only, read

 

 

 

always "0".

25-24 TRANS_MODE

 

Describes the transfer mode for each port.

 

 

00

Reserved (Cut-Through Mode)

 

 

01

Store & Forward Mode

 

 

1x

Reserved

23

DEBUG

 

Mode of operation.

 

 

0b

Normal mode

 

 

1b

Debug mode. The debug mode unlocks capture registers for write and enable debug packet

 

 

 

generator feature.

22

SEND_DBG_PKT

 

Send debug packet. Write 1 force to send debug packet. This bit is set by software and cleared

 

 

 

after debug packet is sent. Writes when the bit is set are ignored. Debug mode only.

21

ILL_TRANS_EN

 

Illegal Transfer Error reporting Enable. If enabled, the Port-Write and interrupt are reported errors.

 

 

0b

Disables Illegal Transfer Error reporting

 

 

1b

Enables Illegal Transfer Error reporting

20

ILL_TRANS_ERR

 

Illegal Transfer Error. It is set to 1 as following:

 

 

 

∙

Received transaction has reserved tt field

 

 

 

∙

Reserved field of Maintenance transaction type

 

 

 

∙

DestID is not defined in look-up table

 

 

 

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 is also reported in registers SP0_ERR_DET and ERR_DET.
