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

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.

CIM_MemoryMappedIO

The CIM_MemoryMappedIO class described in properties Table below addresses both memory and port

I/O resources for personal computer architecture memory mapped I/O.
