SRIO Registers

Table 183. Port Control Independent Register n (SPn_CTL_INDEP) Field Descriptions (continued)

Bit	Field	Value	Description
23	DEBUG		Mode of operation.
		0	Normal mode
		1	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 to force the sending of a 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.
		0	Disable illegal transfer error reporting.
		1	Enable illegal transfer error reporting.
20	ILL_TRANS_ERR		Illegal Transfer Error. After being set, the ILL_TRANS_ERR bit remains set until
			written with a 1, or until a value of all 0s is written to the register
			SP0_ERR_DET.
		0	No error condition detected
		1	One of the following error conditions has been detected:
			∙	The received transaction has a reserved value in the tt field.
			∙	A reserved field of Maintenance transaction type is detected.
			∙	The destination ID is not defined in look-up table.
			This error is also reported in registers SP0_ERR_DET and ERR_DET.
19–18	Reserved	0	These read-only bits return 0s when read.
17	MAX_RETRY_EN		Maximum retry error reporting enable. If enabled, the Port-Write and interrupt are
			reported as errors.
		0b	Max retry error report disable
		1b	Max retry error report enable
16	MAX_RETRY_ERR		Maximum retry error. This bit is ignored if max_retry_threshold is 0. Once set,
			the MAX_RETRY_ERR bit remains set until written with a 1, or until a value of
			all 0s is written to the register SP0_ERR_DET.
		0	No error condition detected
		1	max_retry_cnt is equal to max_retry_threshold. The Port-Write request and
			interrupt are generated if enabled. This error is also reported in the register
			SP0_ERR_DET.
15–8	MAX_RETRY_THR		Maximum Retry Threshold Trigger. These bits provide the threshold value for
			reporting an error condition due to possibly broken partner behavior.
		00h	Disable the max_retry_error reporting
		01h	Set the max_retry_threshold to 1
		02h	Set the max_retry_threshold to 2
		...	...
		FFh	Set the max_retry_threshold to 255
7	IRQ_EN		Interrupt error reporting enable. If enabled, the interrupt signal is high when the
			IRQ_ERR is set to 1.
		0	Interrupt error report disable
		1	Interrupt error report enable
6	IRQ_ERR		Interrupt error status
		0	An error has not occurred and/or there is not a Port-Write condition.
		1	An error occurred and there is a Port-Write condition. IRQ_ERR remains at 1
			until software writes a 1 to it.
5–0	Reserved	0	These read-only bits return 0s when read.
