C6657 PSC

Hello,

I want to understand a description below. Actually, there are more peripherals required software control to enable. What does "all other modules" mean? Are they LPSC #0, #1 and #2 which are "Always on" module in the clock domain?

C6657 data manual (SPRS814A) / 3.2 Peripheral Selection After Device Reset (P.67)
-> By default, the PCIe, SRIO, and HyperLink are held in reset and clock-gated. All other modules come up enabled by default and there is no special software sequence to enable.

Regards,
Kazu

    Hello Kazu,

    Yes, by default PCIe, SRIO, and HyperLink are held in reset and clock-gated and the software enables the modules (turns on clocks and de-asserts reset) before these modules can be used. All other modules refers to the modules listed in section 7.3 Power Sleep Controller (PSC).

    The LPSC #0, #1 and #2 are always on domain and you cannot disable it through software.
