The PRU_ICSSG supports two levels of clock gating. First level gates all clocks inside the PRU_ICSSG when requested by the PSC (Power Sleep Controller). The second level allows user software to enable/disable clocks in the clock gating register ICSSG_CGR_REG to some internal modules, as follows:
The appropriate configuration registers block controls its local module set inside PRU_ICSSG.
PRU_ICSSG supports different clock speeds for CORE_CLK and IEP_CLK. Please refer to PRU_ICSSG Integration, for details.
