DPLL Controller Can Get Stuck While Transitioning to a Power Saving State
Low
The DPLL Controller can get stuck if it is in transition to a low power state while its M/N ratio is being programmed.
Before re-programming the M/N ratio, SW has to ensure the DPLL cannot start an idle state transition. SW can disable DPLL idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request active by setting a dependent clock domain in SW_WKUP.
