PRODUCTION DATA.
Several of the peripherals on the 66AK2Hxx are controlled by the Power Sleep Controller (PSC). By default, the PCIe, SRIO, and HyperLink are held in reset and clock-gated. The memories in these modules are also in a low-leakage sleep mode. Software is required to turn these memories on. Then, the software enables the modules (turns on clocks and deasserts reset) before these modules can be used.
If one of the above modules is used in the selected ROM boot mode, the ROM code automatically enables the module.
All other modules come up enabled by default and there is no special software sequence to enable. For more detailed information on the PSC usage, see the KeyStone Architecture Power Sleep Controller (PSC) User's Guide.
