The clock manager (CM) is primarily responsible for generating interface and functional clocks from the internal clocks provided by DPLL_CORE and DPLL_PER. The CM is physically divided into two independent entities: CM_CORE_AON, which is placed in the PD_COREAON always-on power domain, and CM_CORE, which is placed in the PD_CORE switchable power domain. The split is done to provide control over various entities, such as modules, DPLLs, and clocks, during low-power use case scenarios when the PD_CORE power domain can be switched to RETENTION state.
