PRODUCTION DATA.
Clock gating to each logic block is managed by the local power/sleep controllers (LPSCs) of each module. For modules with a dedicated clock or multiple clocks, the LPSC communicates with the PLL controller to enable and disable the clock (or clocks) of that module at the source. For modules that share a clock with other modules, the LPSC controls the clock gating.
Table 6-6 shows the C6654 and C6652 clock domains.
