CardBus interrupts
The dedicated
CINT#
signal on the CardBus is connected directly to the interrupt
controller in the System Control module, as Interrupt #10 (that is, the same as the
INTA#
signal for the PCI bus). Table 286 shows the CardBus-related maskable interrupt
conditions that are reported to the System Control module’s interrupt controller
through the PCI arbiter’s interrupt.
