In r14 spec, there is the following:
6.8.3.3.3 Transition SP1:OOB_AwaitCOMX to SP4:OOB_COMSAS
This transition shall occur after receiving either a COMINIT Detected
message or a COMSAS Detected
message. If COMSAS Detected was received, this transition shall include
a COMSAS Detected argument.
If the ATTACHED SATA PORT SELECTOR bit is set to one in the SMP DISCOVER
response (see 10.4.3.10), the
state machine shall, before the transition:
a) set the ATTACHED SATA PORT SELECTOR bit to zero in the SMP DISCOVER
response; and
b) send a SATA Port Selector Change confirmation to the link layer.
So when connected to the active port of a port selector, after receiving
the COMINIT from the SATA target, the
ATTACHED SATA PORT SELECTOR bit is cleared.
However, Table 272 indicates that the active port of port selector
should still have this bit asserted.
I think should be discussed during letter ballot comment resolution.
Early comments?
