5.39 LSUn Control Register 6 (LSUn_REG6)

There are four of these registers, one for each LSU (see Table 99). LSUn_REG6 is shown in Figure 100 and described in Table 100. For additional programming see Section 2.3.3.

Bit	Field	Value	Description
31–5	Reserved	0000h	These read-only bits return 0s when read.
4–1	COMPLETION_CODE		Indicates the status of the pending command.
		0000b	Transaction complete, no errors (posted/non-posted)
		0001b	Transaction timeout occurred on non-posted transaction
		0010 b	Transaction complete, packet not sent due to flow control blockade (Xoff)
		0011b	Transaction complete, non-posted response packet (type 8 and 13)
			contained ERROR status, or response payload length was in error
		0100b	Transaction complete, packet not sent due to unsupported transaction type or
			invalid programming encoding for one or more LSU register fields
		0101b	DMA data transfer error
		0110b	"Retry" DOORBELL response received, or Atomic test-and-swap was not
			allowed (semaphore in use)
		0111b	Transaction complete, packet not sent due to unavailable outbound credit at
			given priority
		1xxxb	Reserved
0	BSY		Indicates status of the writeable LSU registers
		0	LSU registers available (writable) for next set of transfer descriptors
		1	LSU registers busy with current transfer
