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.
