The power-management port (PMP) is not integrated for DPLLCTRL_SATA. The DPLL_SATA has no retention capabilities. This means the DPLL digital power supply remains switched on during all modes of operation.
The low-power (LP) modes supported by DPLL_SATA are idle-bypass low power and MN-bypass modes, which are both characterized by:
For more details on the PLL settings and conditions necessary to enter idle-bypass and MN-bypass low-power modes, see Section 28.1.4.3.6.4, SATA DPLL Idle-Bypass Low-Power Mode, and Section 28.1.4.3.6.5, SATA DPLL MN-Bypass Mode.
DPLL_SATA is held in a similar low-power state (DCO and LDO switched off, with CLKDCOLDO = 0) after POR, before the first PLL_GO command has been software-triggered on the PLL controller. See Section 28.1.4.3.6.1, SATA Clock Generator Power Up.
