12-2. Link Power Management State
Serial ATA interface power states are controlled by the device and host controller.
The interface power states are defined as below.
PHYRDY
The Phy logic and main PLL are both on and active. The interface is synchronized and
capable of receiving and sending data.
PARTIAL
The Phy logic of SATA interface is powered, but is in a reduced power state.
Power dissipation in this mode is less than the PHYRDY mode, but more than the SLUMBER mode.
The exit latency from this state shall be no longer than 10 us.
SLUMBER
The Phy logic of SATA interface is powered, but is in a reduced power state.
Power dissipation in this mode is less than the PARTIAL mode.
The exit latency from this state shall be no longer than 10 ms.
