This section describes the SATA PHY subsystem-related components (SATA_PHY, DPLL_SATA, DPLLCTRL_SATA, OCP2SCP3) integration in the device, including information about clocks, resets, and hardware requests.
Figure 28-3 shows the SATA_PHY integration.
The SATA_PHY module integration features are:
The DPLL_SATA integration features are:
The DPLLCTRL_SATA integration features are:
Table 28-2 through Table 28-4 summarize the integration of the module in the device.
