PRIORITY
Priority Level
Every interrupt source must be assigned a priority level during
initiation. Among them, priority level 0 has the highest priority and
priority level 7 the lowest. Interrupt sources with priority level 0 are
promoted to FIQ. Interrupt sources with priority level other than 0
belong to IRQ. For interrupt sources of the same priority level that
located in the lower channel number has higher priority.
