IRQ (Interrupt Request) lines are system resources allocated to I/
O devices. When an I/O device needs to gain attention of the
operating system, it signals this by causing an IRQ to occur. After
receiving the signal, when the operating system is ready, the system
will interrupt itself and perform the service required by the I/O
device.
Primary INTR
Setting ON will cause the system to wake up from power saving
modes if activity is detected from any enabled IRQ channels. Setting
options: ON, OFF.
IRQ3~IRQ15
IRQ3~IRQ15 enable or disable the monitoring of the specified IRQ
lines. If set to Enabled, the activity of the specified IRQ line will
prevent the system from entering power saving modes or awaken it
from power saving modes.
