TriggerLevel Indicates whether 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 whether edge (value=4) or level
triggered (value=3) interrupts occur.

Shareable Indicates whether the IRQ can be shared.
A value of TRUE indicates that the IRQ can be
shared.
Boolean
Hardware Indicates whether 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
notified 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.
