3.2 Peripheral Selection After Device Reset
Several of the peripherals on the TMS320C6672 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. The software enables the modules (turns
on clocks and de-asserts reset) before these modules can be used.
If one of the above modules is used in the selected ROM boot mode, the ROM code will automatically enable 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 Power Sleep Controller (PSC) for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 69.
3.3 Device State Control Registers
The TMS320C6672 device has a set of registers that are used to provide the status or configure certain parts of its
peripherals. These registers are shown in Table 3-2.
