How can power down the unused corepac of c6678?

Please refer to the C66x CorePac users guide (SPRUGW0B) for related documentation.

Each core has its own power down controller (PDC) that can be used to place a core in a low power state independent of others. Some aspects of power down are dynamic (example, L1P, L2 and caches. Sections 12.2.1 to 12.2.3 of SPRUGW0B). Others are software controllable as follows: (Sections 12.2.4 to 12.2.6).

- To power down just the DSP, simply execute an IDLE instruction. Interrupts are required to wake up the DSP (Section 2.12.4).

- To power down the entire CorePac, follow the steps for C66x power down (Section 2.12.5).

- Powering down the CorePac driven by an external interrupt (Section 2.12.6)

Note: The Power sleep controller does not have the ability to clock gate a CorePac (the core clock domain is always ON).

Is the package K1_STK_v1.1 released by TI? If yes, can you please point me to the download link.

Thank you.
