The SATA PLL controller and SATA DPLL clock generator share a common hardware nonretention reset (L3INIT_RST) which comes from the device power and reset manager. When the DPLL_SATA hardware reset completes, the DPLLCTRL_SATA.PLL_STATUS[0] PLLCTRL_RESET_DONE bit is automatically updated to 1. For more information on the hardware reset source, see Reset Domains, in Power, Reset, and Clock Management.
The DPLLCTRL_SATA itself has no software reset capabilities.
The DPLLCTRL_SATA performs a software reset sequence on the DPLL_SATA in hardware (through the TINITZ signal activation).
