11.6.2 Round-robin Scheduling
To avoid the possible starvation problem for low-level interrupts with static priority, where some interrupts might never be
served, the PMIC offers round-robin scheduling for low-level interrupts. When round-robin scheduling is enabled, the
interrupt vector address for the last acknowledged low-level interrupt will have the lowest priority the next time one or
more interrupts from the low level is requested.
