Hot-Plug Interrupt Mask - Intel 460GX Software Developer’s Manual

into this register. Writing a logic 1 will clear the pending interrupt. If there are no other pending
interrupts on the bit, the bit will clear. This register takes on a value based on the monitored status
of the slots and therefore has no particular default value.

Hot-Plug Interrupt Mask

Address Offset:
Default Value:
This read/write mask register is used to indicate which inputs should generate interrupts and which
should not. The mask bits in this register map one-for-one with the HIICR (Interrupt Input and
Clear Register) bits. If a state change occurs on an input while the mask bit for that input is set to
one, then no interrupt will be generated for that state change. If the mask bit is cleared, then an
interrupt will be generated on the next state change.
