SERIAL ATA II: PORT MULTIPLIER / PORT SELECTOR
REV. 1.05
s 0001b = Transition to the Partial power management state initiated
s 0010b = Transition to the Slumber power management state initiated
s 0100b = Transition to the active power management state initiated
s All other values reserved
Bits [11:8] IPM
The IPM field represents the enabled interface power management states that may be invoked via the Serial
ATA interface power management capabilities
s 0000b = No interface power management state restrictions
s 0001b = Transitions to the Partial power management state disabled
s 0010b = Transitions to the Slumber power management state disabled
s 0011b = Transitions to both the Partial and Slumber power management states disabled
s All other values reserved
Bits [7:4]SPD
The SPD field represents the highest allowed communication speed the interface is allowed to negotiate when
interface communication speed is established
s 0000b = No speed negotiation restrictions
s 0001b = Limit speed negotiation to a rate not greater than Gen 1 communication rate
s 0010b = Limit speed negotiation to a rate not greater than Gen 2 communication rate
s All other values reserved
Bits [3:0] DET
The DET field controls the host adapter device detection and interface initialization.
s 0000b = No device detection or initialization action requested
s 0001b = Perform interface communication initialization sequence to establish communication. This is
functionally equivalent to a hard reset and results in the interface being reset and communications
reinitialized. Upon a write to the SControl register that sets the DET field to 0001b, the host interface
shall transition to the HP1: HR_Reset state and shall remain in that state until the DET field is set to a
value other than 0001b, by a subsequent write to the SControl register.
s 0100b = Disable the Serial ATA interface and put Phy in offline mode.
s All other values reserved
