Phys shall use ALIGN (0) to construct OOB signals as described in 6.6. Phys shall 
use ALIGN (0) and ALIGN (1) during the speed negotiation sequence as 
described in 6.7.4.2. Phys shall rotate through ALIGN (0), ALIGN (1), ALIGN 
(2), and ALIGN (3) for all ALIGNs sent after the phy reset sequence. 
1.4.3.3 
BREAK 
The BREAK primitive is used to cancel the connection request, or to cancel the 
connection.  The BREAK primitive is sent in cases 1) to 4) shown below. 
1)  When the connection request is to be canceled after sending an OPEN frame 
2)  When neither OPEN_ACCEPT nor OPEN_REJECT primitive is received 
within 1 ms of sending an OPEN frame  
3)  When neither a DONE primitive nor an SSP frame is received within 1 ms of 
sending a DONE primitive 
4)  When a CLOSE primitive is not received within 1 ms of sending a CLOSE 
primitive 
When the BREAK primitive is sent in any of the cases above, the BREAK timer 
(1 ms) is started in anticipation of the reception of the BREAK primitive within 1 
ms.  If the BREAK primitive is not received within 1 ms, the connection is 
regarded as having been closed. 
After the BREAK primitive is sent, when any primitives and/or frames other than 
the BREAK primitive are received, all of these (except NOTIFY primitives) are 
discarded. 
When the BREAK primitive is not received within 1 ms of sending the BREAK 
primitive, a drive may start the link reset sequence. 
1.4.3.4 
BROADCAST 
BROADCASTs are used to notify all SAS ports in a domain of an event. 
When an expander port receives a BROADCAST it shall transmit the same 
BROADCAST on at least one phy in all other expander ports. BROADCAST shall 
only be sent outside of connections after the phy reset sequence has completed. 
BROADCAST (CHANGE) is sent by an expander device to notify SAS INIT 
ports and other expander devices that a configuration change has occurred. 
BROADCAST (CHANGE) may also be transmitted by SAS INIT ports. 
BROADCAST (CHANGE) shall be ignored by SAS TARG ports. 
BROADCAST (SES) is sent by a SAS TARG port to notify SAS INIT ports that 
an asynchronous event has occurred in an enclosure, and SSP INIT ports should 
poll all the SCSI enclosure services logical units in the SAS domain. 
BROADCAST (SES) shall be ignored by SAS TARG ports. 
The drive ignores all received BROADCAST primitives.
