The Power/Clock Control Block (PCCB) provides separate communication channels to pass information about the power and clock management between the SoC and the network.
The PCCB acts as an aggregator to convey information between the SoC and the other CCN-502 components, in the following manner:
The PCCB receives transaction activity indicators from other relevant CCN-502 components and conveys that information to the external power and clock control units.
When the PCCB receives a power or clock control management request from the external power or clock control units, it conveys that request to the relevant CCN-502 components, where applicable.
The PCCB waits for the appropriate responses from the relevant CCN-502 components, and conveys an aggregated response to the external power and clock control units.
