system by sending an interrupt request. When the system is in Suspend mode, IRQ activity can cause a Primary or Secondary wake-up. When Primary INTR is On, the IRQs in the above fields can be configured as Primary, Secondary, or Disabled.

Primary

The system wakes up fully when it detects IRQ activity.

 

 

 

The system does not wake up, but the interrupt request is

 

processed. Secondary interrupts are typically

 

housekeeping devices needed to maintain the system while

Secondary

not requiring the use of the rest of the system resources.

 

For example, IRQ8, the RTC Alarm, is configured as

 

Secondary by default. Another example might be a

 

network adapter continually polled by the network.
