Round-robin scheduling
Figure 12-1. Static priority.
To avoid the possible starvation problem for low level interrupts with static priority, the PMIC
gives the possibility for round-robin scheduling for low level interrupts. When round-robin sched-
uling is enabled, the interrupt vector address for the last acknowledged low level interrupt will
have the lowest priority next time one or more interrupts from the low level is requested.
