CreationClassName See Common Properties of Classes string
IRQNumber Identies the interrupt request number. uint32
Availability Indicates the availability of the IRQ. Values
for the Availability property are as follows:
1- Other
2- Unknown
3- Available
4 - In use/not available
5- In use and available
uint16
TriggerLevel Indicates if the interrupt is triggered by the
hardware signal going high or low. Values for
the TriggerLevel property are as follows:
1- Other
2- Unknown
3- Active low
4- Active high
uint16
TriggerType Indicates if edge (value=4) or level triggered
(value=3) interrupts occur.
1- Other
2- Unknown
3- Level
4- Edge
uint16
Shareable Indicates if the IRQ can be shared. A value
of TRUE indicates that the IRQ can be
shared.
Boolean
Hardware Indicates if the interrupt is hardware- or
software-based. (A value of TRUE indicates
that the interrupt is hardware based.) On a
personal computer, a hardware IRQ is a
physical wire to a programmable interrupt
controller (PIC) chip set through which the
microprocessor can be notied of time
critical events. Some IRQ lines are reserved
for standard devices such as the keyboard,
diskette drive, and the system clock. A
software interrupt is a programmatic
mechanism to allow an application to get
the attention of the processor.
