IRQ# Activity
After the time period which you set in the Suspend Mode feature elapses,
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 enabled occurs, the system goes directly back
to Full-on Mode.
If the IRQ activity which is defined as "Disabled" occurs, the system
enters another low power state, Dream Mode. In Dream Mode, the system
will function the same as in Full-on Mode, except that the screen display
remains off until the corresponding IRQ handler finishes, whereupon the
system reverts to Suspend Mode.
For instance, if the system is connected to a LAN and receives an
interruption from its file server, the system will enter Dream Mode to
execute the corresponding calling routine.
The options are: Enabled, Disabled.
The default values of IRQ3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15 are all:
Enabled.
The default value of IRQ8 is: Disabled.
