7.3.2 Clock Domains
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 that module's clock(s) at the source. For modules that share a clock with other modules, the LPSC controls
the clock gating.
