I am working on STP protocol in SAS and I have one doubt regarding STP link
After the SAS phy detects during phy reset sequence that it is connected to a
It issues COMWAKE and after the OOB sequence and speed negotiation are
Phy Layer Ready (SATA) message is sent to link layer.
Now my query is after this SATA_PHY_READY, does identification sequence
If yes, then it is said in the protocol that to transmit Identify Address
frame, Phy Layer
Ready (SAS) message is required and does SATA device will have addesses as
If no, then how exactly does the state machine for Link Layer in case of STP
begin and interface with
SL_CC state machines as these state machines need Enable Disable SAS Link
(Enable) message from SL_IR
State machine which, I suppose do not execute in case of STP?
Please clarify my query.
