After the time period which you set at in Suspend Mode Feature, the system
advances from Doze Mode to Suspend Mode in which the CPU clock stops
and the screen display is off. At this moment, if the IRQ activity which is
defined as Primary occurs, the system goes back to Full-on Mode directly.
If the IRQ activity which is defined as Secondary takes place, the system

Full-on Mode except that the screen display remains off until the
corresponding IRQ handler finishes, then back to Suspend Mode.
For instance, if the system connects to a LAN and receives an interruption
